Procurement Notes

Verify that the specific ordering suffix matches the required packaging format, such as tape and reel or cut tape, as indicated by distributor codes. Confirm the enable pin configuration aligns with system control logic. Ensure the 3.3V supply requirement is met within the application's voltage tolerance. Check lead times against current manufacturer availability, as standard delivery periods may vary based on production schedules.

Selection Notes

Select this component when a 37.5 MHz reference clock is required with low-profile surface-mount integration. The 3.3V operation makes it suitable for modern low-voltage digital environments. Consider the ±10ppm stability for applications demanding tight frequency accuracy. The enable feature allows for dynamic power control, which is beneficial for battery-operated devices or systems requiring clock gating capabilities during idle states.
