Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before integration. Ensure the 1.8V supply voltage aligns with the target system design. Confirm that the 4-SMD no-lead package footprint matches the PCB layout constraints. Check for any RoHS compliance documentation if required by the end product specifications.

Selection Notes

Select this component when a 95.625 MHz clock source is required with low voltage operation. The LVCMOS output ensures compatibility with standard digital logic families. The standby feature offers power efficiency benefits for battery-operated or portable applications. Consider the physical size of the 2.0x1.6mm package for assembly feasibility.

Part Context

This part belongs to the QHTF series of oscillators from Mercury Electronics. The series typically includes various frequencies and voltage options. Similar models like the 18QHTF21-96.768-PD share the same package and voltage characteristics but differ in frequency. The 'PD' suffix indicates the inclusion of a power down capability.

Replacement Considerations

Direct substitutes must match the 95.625 MHz frequency, 1.8V supply, and LVCMOS output. Models such as 18QHTF21-96.768-PD are similar in form factor but have different frequencies. Verify pinout and electrical parameters before substitution.
