Procurement Notes

Verify the specific suffix (E vs ET) against the manufacturer's official documentation to confirm packaging and tape-and-reel specifications. Confirm current availability status as distribution channels may list limited stock or end-of-life notifications. Ensure the ordering part number matches the exact electrical and mechanical requirements defined in the latest datasheet revision.

Selection Notes

Select this component when a low-noise, wideband frequency divider is required for signals up to 6 GHz. The SiGe BiCMOS process offers a balance of speed and noise performance suitable for RF front-ends. Consider the 16-pin QFN footprint for PCB layout constraints and verify that the 5V supply requirement aligns with the system power architecture.
