Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the LVPECL output swing matches your receiver input specifications. Ensure the 3.3V supply rail provides adequate current capability for the oscillator startup and steady-state operation. Check for RoHS compliance documentation if required by your manufacturing standards.

Oscillators Selection Notes

Select this component when a precise 16.357 MHz reference is needed with tight frequency stability. The LVPECL output is ideal for differential signaling paths requiring low jitter. Consider the 3.3V supply constraint and the physical dimensions of the 6-SMD package during PCB layout. Evaluate thermal management needs based on the expected ambient temperature range to maintain the ±2.5 ppm specification.

Oscillators Part Context

This part belongs to the QuikXO TCXO series from Mercury Electronics, designed for applications requiring reliable clock sources in portable and industrial electronics. The QMQF326P33 designation indicates a specific footprint and pin configuration common to Mercury's compact oscillator lineup. It serves as a critical timing element in systems where frequency drift due to temperature changes must be minimized.

Oscillators Replacement Considerations

Direct replacements must match the 16.357 MHz frequency, ±2.5 ppm stability, LVPECL output type, and 3.3V supply voltage. Verify that any substitute component fits the same 6-SMD no-lead footprint. Cross-reference datasheets for equivalent thermal characteristics and aging rates to ensure system performance remains unaffected.
