Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints to guarantee proper assembly and electrical connectivity.

Oscillators Selection Notes

Select this component when a precise 16.777216 MHz reference is required for video or audio applications. The choice depends on the need for a small 2.0x1.6 mm form factor and low power consumption via the standby feature. Consider the LVCMOS interface compatibility with your target logic family.

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. The 'PD' suffix indicates the inclusion of a power-down pin for active control. This specific model targets space-constrained portable electronics requiring stable timing.

Oscillators Replacement Considerations

Direct substitutes must match the 16.777216 MHz frequency, 1.8V supply, and 4-SMD 2.0x1.6mm package. Verify equivalent LVCMOS output characteristics and power-down functionality. Cross-reference with other Mercury QHTF variants or industry-standard equivalents ensuring identical pinout and thermal properties.
