Oscillators Procurement Notes

Verify the specific output configuration and pinout compatibility against your circuit schematic before integration. Confirm that the 3.3V supply rail meets the current consumption requirements specified in the official datasheet. Ensure the PCB footprint matches the 7.0x5.0mm SMD dimensions to prevent mechanical mounting issues during assembly.

Oscillators Selection Notes

Select this model when a stable 19.2 MHz reference signal is required for high-performance digital interfaces. The LVPECL output is suitable for long-distance transmission with low noise characteristics. Consider the ±1.0 ppm stability if tight timing accuracy is critical for system synchronization compared to standard XO alternatives.

Oscillators Part Context

This component belongs to the MQF576 series of TCXOs from Mercury Electronics. The series offers various frequencies up to 1.5 GHz with options for LVPECL or LVDS outputs. The MQF576P33 variant specifically denotes the 3.3V supply version within the 7.0x5.0mm form factor family designed for demanding communication applications.

Oscillators Replacement Considerations

Direct substitutes include other MQF576 series parts with identical frequency and output type, such as MQF576D33-19.200-1.0/-40+85 if LVDS output is acceptable. Verify electrical parameters and pin assignments before swapping components to ensure functional equivalence.
