Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any specific handling instructions related to the surface mount technology used in this component.

Selection Notes

Select this oscillator when a 119.93 MHz frequency is required with LVCMOS compatibility. Consider the 1.8V operating voltage for low-power applications. The small 2.0x1.6 mm package is suitable for space-constrained designs. Evaluate the need for standby functionality if power management is a priority in the target application environment.

Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies with consistent LVCMOS outputs and low-voltage operation. The 'PD' suffix typically indicates the inclusion of power-down capabilities. These components are widely used in consumer electronics and industrial equipment where size and power efficiency are critical factors.

Replacement Considerations

Direct substitutes may include other 119.93 MHz LVCMOS oscillators in a 4-SMD no-lead package. Verify pinout compatibility and electrical specifications such as supply voltage and output swing. Alternative parts from different manufacturers must match the physical dimensions and thermal characteristics to ensure proper integration.
