Oscillators Procurement Notes

Verify the specific part number suffix against official Mercury documentation to confirm voltage and frequency specifications. Ensure compatibility with the target PCB footprint for the 4-SMD no lead package. Confirm RoHS compliance status through the manufacturer's current datasheet before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a small form factor oscillator with low EMI characteristics is required for digital circuits. The integrated enable pin allows for power management strategies. Verify that the 43.4835 MHz frequency meets system requirements and that the -45°C to 85°C temperature range covers the operational environment.

Oscillators Part Context

This SSXO belongs to Mercury's series of miniature crystal oscillators designed for space-constrained applications. The 3QHM53D4.0 prefix indicates the package style and series family, while the numeric suffix specifies the exact output frequency. These components are active products intended for high-reliability electronic assemblies.

Oscillators Replacement Considerations

Direct substitutes must match the 43.4835 MHz frequency, 4-SMD package, and CMOS output type. Verify electrical parameters such as supply voltage and operating temperature range.
