Procurement Notes

Verify the specific part number against official Mercury Electronics documentation to confirm current availability status. Distributor listings may indicate discontinuation or limited stock. Ensure the required operating temperature range and voltage specifications match the target application requirements before procurement. Cross-reference datasheet parameters for accuracy.

Selection Notes

Select this component when a 1.8V LVCMOS oscillator with enable control is required. Consider the 4-SMD package size for space-constrained designs. Verify that the 13.26225 MHz frequency meets system timing needs. Check if the standard output type suffices for the load capacitance requirements of the connected microcontroller or FPGA.

Part Context

This model belongs to the QHTF series of surface mount oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options. The 'OE' suffix often denotes specific packaging or tape-and-reel configurations in distributor catalogs. This component represents a standard solution for low-voltage digital clocking applications.

Replacement Considerations

Direct substitutes must match the 1.8V supply, LVCMOS output, and 4-SMD package. Verify frequency tolerance and phase jitter specifications against the original datasheet. Alternative manufacturers may offer similar pin-compatible devices, but electrical characteristics must be validated for functional equivalence.
