Frequently Asked Questions(FAQ)

How does the ASD1-14.31818MHZ-LR-T oscillator’s frequency stability of ±25ppm impact clock synchronization accuracy in a 14.31818 MHz system over its full operating temperature range?
Over the -40°C to 85°C range, a ±25ppm stability results in a maximum frequency deviation of approximately ±3.58 kHz from the nominal 14.31818 MHz. This level of variation can affect timing margins in high-speed digital systems if not compensated for in firmware or design assumptions, particularly in applications requiring precise sample timing or tight phase alignment across multiple clock domains.
What is the total current consumption when the ASD1-14.31818MHZ-LR-T is enabled versus disabled, and how should this be factored into power-sensitive embedded designs?
When active, the device draws up to 4mA at 3V supply voltage, resulting in 12mW power dissipation. In shutdown mode, it consumes only up to 20µA, which reduces power to 60µW. Designers should account for this difference by enabling the oscillator only during active processing phases and using the disable function during idle periods to minimize energy use in battery-powered applications.
Can the ASD1-14.31818MHZ-LR-T be used as a drop-in replacement for standard crystal oscillators in legacy video timing circuits, and what layout considerations are necessary?
Yes, the ASD1-14.31818MHZ-LR-T operates at the commonly used 14.31818 MHz frequency found in NTSC video systems. However, unlike passive crystals, it includes integrated drive circuitry and requires proper decoupling near the VDD pin—typically with a 100nF capacitor placed within 5mm of the package—to maintain signal integrity and prevent noise coupling into adjacent traces.
How does the 4-SMD, no-lead footprint of the ASD1-14.31818MHZ-LR-T compare to traditional SMD packages in terms of soldering reliability and thermal performance?
The 2.50mm x 2.00mm size offers improved solder joint consistency under reflow due to surface tension effects inherent in no-lead designs. While thermal conductivity is slightly lower than leaded counterparts of similar mass, the compact profile reduces parasitic inductance in high-frequency paths, which benefits timing stability more than heat dissipation needs in most low-power oscillator applications.
What precautions should be taken when enabling or disabling the ASD1-14.31818MHZ-LR-T via its control input to avoid transient glitches on downstream logic?
The enable/disable function is asynchronous but not glitch-tolerant; rapid toggling or simultaneous assertion with supply ramp-up can cause undefined output states. It's recommended to sequence power before enabling the device and to debounce or synchronize control signals with the main system clock to ensure clean transitions and prevent metastability issues in synchronous subsystems.
Why might the ASD1-14.31818MHZ-LR-T be preferred over a crystal + inverter solution despite potentially higher cost, and under what design conditions?
Integrating the resonator and feedback network into a single package like the ASD1-14.31818MHZ-LR-T reduces PCB real estate, shortens trace lengths (minimizing parasitic capacitance), and improves manufacturability by eliminating tuning components. This is advantageous in space-constrained or high-volume consumer electronics where board area and assembly yield outweigh unit cost differences.
How does the operating temperature range of -40°C to 85°C influence oscillator performance in automotive vs. industrial environments?
Although rated for -40°C to 85°C, industrial systems often operate near these limits intermittently, while automotive environments may exceed them. The ±25ppm stability is specified across this range, but long-term drift and aging characteristics become more pronounced at temperature extremes. For automotive use, additional margin should be allocated in timing budgets unless the application supports periodic recalibration.
What role does the HCMOS output type play in interfacing the ASD1-14.31818MHZ-LR-T with FPGA input pins, and are termination resistors required?
The HCMOS output provides standard-compliant TTL/CMOS-compatible logic levels compatible with most modern FPGAs without level shifting. Since it drives capacitive loads directly, series termination matching trace impedance (typically 22Ω–33Ω) is advised when routing over 10cm or through vias to dampen reflections and reduce EMI, especially at the 14.31818 MHz fundamental frequency.

    Used this rectifier in a high-current power supply repair. Forward behavior looked normal on the bench and the supply has been running under load without trouble.

  • Retr***UWorks
    Aug 31, 2026

    Needed the exact ST10F269Z2Q6 for servicing an older control unit. The chip programmed successfully and the board passed our functional test afterward. Much easier than redesigning around a newer MCU.
