Oscillators Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to ensure correct voltage and package configuration. Confirm that the 3.3V supply requirement aligns with system design constraints. Check for RoHS compliance status if environmental regulations apply to the end product. Ensure the 4-SMD footprint matches the PCB layout specifications before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a 119.9308 MHz frequency is strictly required for system synchronization. Consider the 3.3V operating voltage to match existing power rails without additional regulation. Evaluate the small 2.0x1.6mm package size for space-constrained designs. Verify compatibility with LVCMOS logic levels used in the target application circuitry.

Oscillators Part Context

This part belongs to the QHTF series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and voltage options within a standardized small outline package. These components are designed for applications demanding reliable frequency stability in compact electronic devices.

Oscillators Replacement Considerations

Direct substitutes must match the 119.9308 MHz frequency, 3.3V supply, and LVCMOS output. Verify pinout compatibility for the 4-SMD no-lead package. Cross-reference with other Mercury QHTF variants or equivalent industry parts ensuring identical electrical parameters.
