Procurement Notes

Verify the specific ordering suffix to confirm the exact output voltage level, temperature range, and packaging configuration required for your design. Ensure the selected variant matches the necessary frequency stability and jitter specifications for the target application environment. Cross-reference the datasheet revision date to confirm current manufacturing status and compliance certifications before finalizing procurement orders.

Selection Notes

Select this component when a low-jitter VCXO with multiple frequency options is required for high-speed data transmission. The LVDS output is suitable for noise-sensitive digital interfaces. Consider the 5x7 mm footprint for space-constrained PCB layouts. Verify that the 3.3V supply voltage aligns with the system power architecture and that the enable pin functionality meets control logic requirements.

Part Context

This part belongs to the M31x series of Multiple Frequency VCXOs. The series leverages fundamental 3rd overtone crystals combined with specialized IC technology to replace traditional SAW devices. It offers improved long-term reliability and phase noise performance compared to conventional multi-crystal solutions, serving as a versatile clock source for various communication protocols.

Replacement Considerations
