Procurement Notes

Verify the specific output configuration and supply voltage requirements against your circuit design before procurement. Confirm that the 9x14 mm package dimensions align with your PCB footprint constraints. Ensure compatibility with the CML output interface levels. Check for any specific ordering suffixes that may denote temperature ranges or enable/disable logic variations if required by your application specifications.

Selection Notes

Select this component when low phase noise and tight thermal stability are critical for signal integrity. The VCXO architecture allows for frequency tuning, making it suitable for applications requiring precise clock adjustments. Consider the 3.3V power requirement and CML output drive strength. Evaluate the 0.35 ps RMS jitter specification against your system's timing budget to ensure compliance with high-speed data transmission standards.

Part Context

This part belongs to the M320x series of Voltage Controlled Crystal Oscillators. The series is characterized by its use of QiK Chip™ technology and availability in various output formats such as LVPECL, LVDS, and CML. These oscillators are designed for demanding circuit applications requiring excellent phase noise and jitter performance within a compact industry-standard package form factor.

Replacement Considerations

Direct substitutes within the same series include other M320x variants with different frequencies or output types, such as M32002AUMJ or M32002BUPJ. Verify that alternative parts match the required frequency, output interface, and package dimensions. Cross-reference datasheets to ensure equivalent jitter and phase noise specifications are maintained for the target application.
