Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system's power rails. Ensure the PCB layout accommodates the 2.0x1.6mm package dimensions and soldering specifications for 4-SMD no-lead components. Cross-reference the part number suffix PD with manufacturer documentation to confirm availability and exact electrical characteristics.

Oscillators Selection Notes

Select this component when a small form factor oscillator is required for 1.8V logic systems. The LVCMOS output is appropriate for direct interfacing with standard digital inputs without additional level shifting. Consider the operating temperature range specified in the datasheet to ensure reliability under environmental conditions. The standby feature makes it suitable for battery-powered devices where power efficiency is critical.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies within the same physical package, allowing for design flexibility. The 'PD' suffix typically indicates a specific packaging or tape-and-reel configuration. These oscillators are part of Mercury's broader portfolio of frequency control products, which includes crystals and resonators.

Oscillators Replacement Considerations

Direct replacements must match the 22.602 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package size. Verify pin compatibility and electrical parameters such as jitter and phase noise. Consult the manufacturer's cross-reference list for approved substitutes. Ensure any alternative component supports the same standby functionality if power management is required.
