Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Check for RoHS compliance if required by your manufacturing standards. Validate the operating temperature range suitability for your final application environment.

Selection Notes

Select this component when a low-profile, 1.8V LVCMOS oscillator is required for space-constrained designs. Consider the 11.110 MHz frequency specifically for timing applications requiring this exact rate. Evaluate the standby feature if power efficiency during idle periods is critical. Compare against other Mercury QHT series parts for alternative frequencies or package sizes if needed.

Part Context

This part belongs to the Mercury QHT series of high-performance crystal oscillators. The series is known for providing stable clock signals in small form factors. Mercury Electronics specializes in frequency control products, including crystals and oscillators, serving various electronic industries globally.

Replacement Considerations

Direct substitutes may include other 11.110 MHz LVCMOS oscillators in 2.0x1.6mm packages from different manufacturers. Verify pin compatibility and electrical specifications such as current consumption and jitter performance. Cross-reference with Mercury's own product line for variants with different suffixes indicating alternate packaging or testing conditions.
