• Integrated standby or power down capability
• Compact 4-SMD no lead surface mount package

Oscillators Applications

• General clock signal generation in electronic circuits
• Timing reference for low-voltage digital systems
• Embedded system clock sources

Oscillators Procurement Notes

Verify the specific suffix 'PD' corresponds to the required power-down functionality and packaging configuration. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the 2.0x1.6 mm footprint matches the PCB layout constraints. Check for RoHS compliance status if environmental regulations apply to the end product.

Oscillators Selection Notes

Select this component when a precise 22.118 MHz timing source is required for 1.8V logic families. Consider the small form factor for space-constrained designs. Evaluate the need for power management features provided by the standby mode. Compare against other frequencies in the 18QHTF21 series if exact frequency matching is not critical.
