Frequently Asked Questions(FAQ)

What are the key electrical characteristics of the SG-8101CA 112.6400M-TCHSA0 oscillator that impact power-sensitive RF front-end designs?: The SG-8101CA 112.6400M-TCHSA0 operates at a supply voltage range of 1.8V to 3.3V, making it compatible with low-voltage digital basebands and analog RF subsystems. Its typical supply current is 6.8mA during active operation, which should be factored into thermal and battery life calculations for mobile or handheld devices. In standby mode, the device draws only 1.1µA maximum, enabling efficient power management when the clock signal is not required. These characteristics support integration in systems where dynamic power gating is employed across multiple functional blocks.

How does the frequency stability specification of ±20ppm affect system timing accuracy in 5G NR sub-6 GHz applications using the SG-8101CA 112.6400M-TCHSA0?: Over the operating temperature range of -40°C to 105°C, the SG-8101CA 112.6400M-TCHSA0 maintains ±20ppm frequency stability, which translates to approximately ±2.25 MHz variation in output frequency at 112.64 MHz. For time-critical protocols like 5G NR, such drift can influence symbol synchronization and error vector magnitude (EVM) performance if not compensated by calibration or disciplined clocking. Designers must ensure that timing recovery loops and phase-locked loops (PLLs) are robust enough to accommodate this level of variation without degrading throughput or increasing bit error rates.

Can the SG-8101CA 112.6400M-TCHSA0 be used as a reference clock in a multi-carrier base station architecture, and what are the implications of its CMOS output type?: Yes, the SG-8101CA 112.6400M-TCHSA0 is suitable as a local oscillator reference in multi-carrier infrastructure due to its precise 112.64 MHz output and low jitter performance implied by Epson’s SG-8101 series reliability. However, its CMOS output requires careful termination and fan-out considerations when driving multiple PLL inputs across different ICs. Unlike differential outputs, CMOS levels are susceptible to noise coupling over longer traces, so layout practices such as controlled impedance routing and guard traces should be followed to preserve signal integrity in high-density boards.

How does the Moisture Sensitivity Level (MSL) rating of 1 for the SG-8101CA 112.6400M-TCHSA0 influence handling procedures during PCB assembly?: With an MSL rating of 1, the SG-8101CA 112.6400M-TCHSA0 is considered moisture-insensitive under normal storage conditions and does not require bake-out prior to reflow soldering. This simplifies manufacturing logistics and reduces processing steps compared to components with higher MSL ratings. As long as standard IPC Class 3 cleanroom or equivalent handling standards are observed during unpacking and placement, the risk of popcorning or delamination during thermal cycling is minimized, supporting reliable mass production.

What trade-offs exist between using the SG-8101CA 112.6400M-TCHSA0 versus a TCXO or OCXO for high-accuracy wireless backhaul systems?: While the SG-8101CA 112.6400M-TCHSA0 offers excellent cost efficiency and compact size with ±20ppm stability, TCXOs typically achieve ±0.5ppm to ±2ppm and OCXOs ±0.01ppm or better, albeit at higher power and larger footprints. For applications requiring tighter phase noise and long-term drift control—such as point-to-point microwave links—a TCXO or OCXO may be preferable despite their increased BOM cost and thermal sensitivity. The choice hinges on whether system-level budget allows margin for clock discipline versus upfront oscillator precision.

Is the SG-8101CA 112.6400M-TCHSA0 compatible with automated pick-and-place equipment commonly found in high-volume SMT lines?: Yes, the SG-8101CA 112.6400M-TCHSA0 is packaged in Tape & Reel (TR) format, which is fully compliant with industry-standard feeder systems used in automated surface mount technology (SMT) assembly. The 4-SMD, no-lead package measures 7.00mm x 5.00mm and aligns with common reel specifications for passive and active components. This enables seamless integration into high-throughput manufacturing environments without requiring special handling or custom tooling, reducing setup time and improving yield predictability.

How does the operating temperature range of -40°C to 105°C affect oscillator performance in industrial edge computing nodes deployed in outdoor enclosures?: The extended operating range of the SG-8101CA 112.6400M-TCHSA0 ensures reliable operation in harsh environments such as roadside traffic controllers or surveillance cameras exposed to direct sunlight or cold winters. However, within this span, frequency deviation remains bounded by the ±20ppm stability spec, so designers should still account for potential shifts during extreme transient conditions. Thermal gradients across the PCB can also induce mechanical stress near the oscillator package, necessitating adequate copper pour isolation and via stitching to maintain consistent junction temperatures.

What considerations apply when cascading the SG-8101CA 112.6400M-TCHSA0 with a downstream frequency multiplier in a software-defined radio (SDR) platform?: When multiplying the 112.64 MHz output of the SG-8101CA 112.6400M-TCHSA0, accumulated phase noise and harmonic content from both the oscillator and multiplier stages degrade overall spectral purity. Since the oscillator exhibits typical CMOS-level rise/fall times, care must be taken to match input capacitance and drive strength at the multiplier’s clock input to avoid ringing or excessive loading. Additionally, feedback loops in the multiplier may amplify any residual instability from the source clock, so loop bandwidth and damping factors must be carefully tuned to prevent oscillation.

How does the RoHS3 compliance status of the SG-8101CA 112.6400M-TCHSA0 impact regulatory documentation for medical device certification?: RoHS3 compliance means the SG-8101CA 112.6400M-TCHSA0 meets the latest European Union restrictions on hazardous substances, including stricter limits for DEHP, BBP, DBP, and DIBP. This simplifies CE marking and global market access for medical electronics manufacturers who must demonstrate full supply chain conformance. Inclusion of this part in product declarations of conformity (DoC) avoids additional testing or exclusion clauses, streamlining audit readiness and reducing time-to-market for Class II or III medical devices relying on stable RF timing sources.

What role does the Base Product Number SG-8101 play in selecting alternative oscillators for the SG-8101CA 112.6400M-TCHSA0?: The SG-8101 family provides a coherent design ecosystem with standardized pinouts, package dimensions, and electrical interfaces across variants differing in frequency, voltage, and trim options. When evaluating alternatives to the SG-8101CA 112.6400M-TCHSA0, matching the Base Product Number ensures drop-in compatibility without redesigning layout or firmware. Manufacturers often use this approach to maintain inventory flexibility while meeting specific frequency requirements, provided that environmental and performance constraints are verified independently.

Why might a designer choose the SG-8101CA 112.6400M-TCHSA0 over a crystal resonator paired with an external buffer IC?: Integrated CMOS oscillators like the SG-8101CA 112.6400M-TCHSA0 reduce board real estate, eliminate parasitic effects from discrete traces, and simplify timing budgets by offering calibrated, low-jitter signals out-of-the-box. Using a bare crystal with an external buffer adds component count, increases susceptibility to EMI, and introduces propagation delay uncertainty unless carefully characterized. For space-constrained designs such as wearables or IoT sensors, the all-in-one solution improves reliability and accelerates bring-up cycles.

How does the standby (power-down) function of the SG-8101CA 112.6400M-TCHSA0 support sleep-mode operation in battery-powered wireless sensor networks?: The ability to disable the SG-8101CA 112.6400M-TCHSA0 reduces supply current from 6.8mA down to 1.1µA maximum, effectively cutting active power consumption by over 98%. During deep-sleep intervals common in protocols like LoRaWAN or BLE, this feature enables significant energy savings without losing synchronization state, assuming the host microcontroller preserves relevant registers. Wake-up latency is minimal due to fast startup characteristics inherent in the SG-8101 architecture, allowing rapid return to full-speed operation when events trigger transmission.

What are the implications of the absence of Absolute Pull Range (APR) data for tuning applications involving the SG-8101CA 112.6400M-TCHSA0?: The lack of published APR information indicates that the SG-8101CA 112.6400M-TCHSA0 is not intended for post-manufacturing frequency trimming via varactors or load capacitance adjustment. This simplifies design but restricts use cases requiring fine-tuned frequencies beyond the nominal 112.64 MHz value. Applications such as cognitive radios or adaptive channel hopping would need alternative solutions, whereas fixed-frequency communications like Wi-Fi or LTE baseband modules can leverage the pre-calibrated output directly.

How does the height profile of the SG-8101CA 112.6400M-TCHSA0 compare to other 4-SMD oscillators in dense multilayer PCBs?: At 1.40mm maximum seated height, the SG-8101CA 112.6400M-TCHSA0 occupies moderate vertical space compared to ultra-low-profile alternatives below 0.8mm or taller leaded packages exceeding 3mm. This places it well within typical clearance limits for 1.6mm thick FR4 substrates used in mid-range communication modules, though clearance with tall connectors or heat sinks must still be verified during 3D stackup analysis. Its flat profile supports closer component packing without violating creepage requirements.

Can the SG-8101CA 112.6400M-TCHSA0 drive multiple loads simultaneously without degradation in output waveform quality?: The CMOS output stage of the SG-8101CA 112.6400M-TCHSA0 is designed for moderate fanout; driving more than two comparable CMOS inputs may result in skewed rise/fall times or undershoot due to capacitive loading exceeding driver capability. If multiple loads are required, a buffer or line driver should be inserted close to the destination ICs. Alternatively, distributing clocks through a dedicated clock distribution IC preserves signal integrity and maintains timing margins across complex FPGA or SoC-based designs.

What environmental certifications beyond RoHS apply to the SG-8101CA 112.6400M-TCHSA0 for automotive infotainment systems?: While the datasheet specifies RoHS3 compliance and REACH unaffected status, automotive-grade validation would require additional qualifications such as AEC-Q200 for passive components, which the SG-8101CA 112.6400M-TCHSA0 does not explicitly claim. Therefore, it is suitable for non-powertrain consumer infotainment where environmental stress is moderate, but unsuitable for engine control units or safety-critical systems demanding full automotive certification. Always verify application-specific qualification documents before deployment.

How does the selection of a 112.64 MHz frequency for the SG-8101CA 112.6400M-TCHSA0 benefit video processing pipelines in embedded vision systems?: The 112.64 MHz frequency aligns with common pixel clock rates used in high-definition video capture interfaces such as MIPI CSI-2 lanes operating at 1.485 Gbps or HDMI TMDS clocks derived from fractional dividers. By providing a stable, low-noise reference, the SG-8101CA 112.6400M-TCHSA0 helps maintain color fidelity and synchronization across analog-to-digital converters and image signal processors, reducing artifacts like rolling shutter distortion or chroma subsampling errors in real-time analytics platforms.

What precautions should be taken when storing unused SG-8101CA 112.6400M-TCHSA0 units prior to PCB assembly?: Although rated MSL 1, the SG-8101CA 112.6400M-TCHSA0 should be stored in anti-static packaging at ambient temperature and humidity below 60% RH to prevent electrochemical migration or tin whisker growth over long durations. Prolonged exposure to condensation risks could compromise hermeticity despite the sealed package design. Inventory rotation using FIFO principles minimizes shelf life concerns, and visual inspection for discoloration or seal breach is recommended before use.
