Oscillators Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to confirm exact electrical parameters and packaging options. Ensure that the selected variant matches the required frequency tolerance and operating temperature range for the target application environment. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a balance between high frequency stability and low power consumption is critical. The 3.3 V supply voltage makes it suitable for modern low-voltage digital circuits. Consider the clipped sine wave output compatibility with downstream logic interfaces. Evaluate the physical dimensions against the available PCB real estate to ensure proper mechanical fit during the design phase.

Oscillators Part Context

This model belongs to the JT21 series of surface-mount oscillators from Jauch Quartz. The series is characterized by its small footprint and suitability for applications where size and power efficiency are primary constraints. It represents a specialized solution within the broader quartz oscillator portfolio, focusing on cost-effective precision timing for mass-market electronic devices.

Oscillators Replacement Considerations

Direct substitutes must match the 38.4 MHz frequency, ±2.5 ppm stability, 3.3 V supply, and 2.5x2.0 mm package. Verify pinout compatibility and output waveform type before substitution. Consult the manufacturer's cross-reference guide for validated alternative part numbers.
