Oscillators Procurement Notes

Verify the specific ordering suffix and packaging configuration directly with the manufacturer or authorized distributors before purchase. Ensure that the required operating temperature range and load capacitance specifications align with the target design requirements. Confirm availability of the strip packaging format if applicable to the production line setup.

Oscillators Selection Notes

Select this component when a stable 15.104893 MHz reference is required within space-constrained designs. The 1.8V supply requirement dictates compatibility with low-voltage logic families. Consider the standby feature if power efficiency is critical. Validate that the LVCMOS output swing meets the input thresholds of the downstream receiving circuitry.

Oscillators Part Context

This part belongs to the QHTF series of high-frequency oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options within small form factors. The 'PD' suffix indicates the inclusion of a power-down capability, distinguishing it from continuous-operation variants within the same physical footprint family.

Oscillators Replacement Considerations

Direct replacements must match the 15.104893 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter against the original datasheet to ensure functional equivalence.
