Oscillators Procurement Notes

Verify the specific suffix PD indicates the power-down feature when confirming orders. Ensure the 1.8V supply requirement matches the target circuit design. Confirm the 4-SMD no-lead package footprint aligns with the board layout. Check the datasheet for exact operating temperature limits before integration. Validate that LVCMOS output levels are compatible with downstream logic inputs.

Oscillators Selection Notes

Choose this component when a 48.8392 MHz reference is required with minimal power consumption. The 1.8V supply voltage suits modern low-power digital circuits. The small 2.0x1.6mm footprint is ideal for dense PCB arrangements. Consider the power-down feature if battery life or thermal management is critical. Ensure the LVCMOS output swing meets the input requirements of the connected microcontroller or FPGA.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and voltage options within a standardized small outline package. The PD suffix denotes the inclusion of a power-down control pin, distinguishing it from standard continuous-operation variants. This family targets applications needing precise timing in compact form factors.

Oscillators Replacement Considerations

Direct substitutes must match the 48.8392 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify that any alternative part includes the power-down feature if specified by the PD suffix. Cross-reference the pinout and footprint dimensions to ensure mechanical compatibility. Check electrical specifications such as load capacitance and drive strength for functional equivalence.
