Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Request the official datasheet from Mercury Electronics for precise electrical characteristics and reliability data.

Selection Notes

Select this component when a precise 59.3701 MHz reference is required with low power consumption capabilities. The LVCMOS output is compatible with standard digital logic families. Consider the standby feature for systems requiring power management during idle states. Verify thermal performance within the specified operating temperature range.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies with standardized LVCMOS outputs. The 'PD' suffix indicates the inclusion of power-down control functionality. These components are designed for space-constrained electronic applications requiring stable clock signals.

Replacement Considerations

Direct substitutes must match the 59.3701 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD package. Verify pinout compatibility and electrical parameters such as phase noise and jitter. Consult manufacturer cross-reference lists for equivalent parts from other suppliers.
