Procurement Notes

Verify the specific suffix 'L' against official QST documentation to confirm pinout and mechanical compatibility. Ensure supply voltage requirements match the 3.3V specification. Confirm that the CMOS output level aligns with target circuit design constraints before finalizing procurement orders.

Selection Notes

Select this component when precise frequency stability within ±20ppb is required over wide temperature variations. Consider the 170mA current draw for power budget calculations. Ensure the 6-SMD footprint fits the available PCB space. Verify thermal management capabilities for enclosed environments.

Part Context

This part belongs to the QTO107 series of OCXOs from QST. The series offers various frequencies and stability options. The 19.2 MHz variant is optimized for applications needing stable clock signals. Packaging is typically tape and reel for automated assembly processes.

Replacement Considerations

Direct substitutes include other QST QTO107 variants with matching frequency and stability if pinouts are identical. Cross-manufacturer replacements require verification of voltage, current, and dimensional compatibility.
