Oscillators Procurement Notes

Verify the specific suffix codes against official Mercury documentation to ensure correct voltage and output type compatibility. Confirm RoHS compliance status through the manufacturer's latest datasheet before integration. Cross-reference the part number with authorized distributors to validate authenticity and avoid counterfeit components during sourcing.

Oscillators Selection Notes

Select this model when a 128 MHz reference signal with high precision is required for digital interfaces. The LVPECL output ensures robust signal integrity for high-speed data transmission. Ensure the design accommodates the 2.5V supply rail and the thermal requirements of the -40°C to +85°C operating range for reliable long-term performance.

Oscillators Part Context

This component belongs to the VMQF576 series of surface-mount TCXOs from Mercury Electronics. The series offers flexibility in frequency customization and supports both LVPECL and LVDS outputs. It is engineered for multimedia and network applications where low phase jitter and stable frequency are critical for maintaining data throughput and system reliability.

Oscillators Replacement Considerations

Direct substitutes include other Mercury VMQF576 variants with matching 128 MHz frequency and LVPECL output, such as VMQF576P33-128.000-1.0/-40+85 if 3.3V operation is acceptable. Verify pinout and electrical characteristics before swapping to ensure circuit compatibility.
