Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct pinout and electrical characteristics. Confirm that the OE variant matches the required enable/disable functionality rather than standby modes found in other series variants. Cross-reference the package dimensions and operating temperature range with the target application requirements before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a precise 111.375 MHz reference is required with low-power standby capabilities. Ensure the system design supports 3.3V logic levels and accommodates the 2.0x1.6mm footprint. Consider thermal performance within the specified -40°C to +85°C range during initial circuit planning.

Oscillators Part Context

This oscillator belongs to the 3QHTF21 series from Mercury Electronics, which specializes in quartz frequency control products. The series includes various XO types with different frequencies and control functions. Mercury Electronics has extensive experience in manufacturing crystal oscillators and related components since 1973.

Oscillators Replacement Considerations

Direct substitutes may include other 111.375 MHz LVCMOS oscillators in 2.0x1.6mm packages with enable pins. Verify electrical parameters and pin assignments carefully. Alternative part numbers should be confirmed through official cross-reference tools or manufacturer datasheets.
