Procurement Notes

This part number is obsolete and no longer manufactured. Designers should verify end-of-life status before procurement attempts. Alternative components such as the NB3V8312CFAG are available from other manufacturers like onsemi. Verify RoHS compliance (RoHS3) and moisture sensitivity level (MSL 3) requirements for assembly processes.

Selection Notes

Select this component when a 2:12 clock fan-out with multi-standard input compatibility is required. Ensure the design accommodates the 32-LQFP package dimensions (7x7 mm). Verify that the supply voltage constraints (2.375V–3.465V) align with the system power rails. Note that the device is discontinued; evaluate replacement parts for pin compatibility and electrical parameter equivalence.

Part Context

The 83948AYILF belongs to the ICS83948A family of clock buffers. It is produced by Renesas Electronics Corporation. The specific suffix 'AYI-147LFT' denotes the package type, temperature range, and tape-and-reel packaging. The base model number is 83948A.

Replacement Considerations

The NB3V8312CFAG from onsemi is listed as a similar alternative. Verify functional equivalence regarding input/output ratios and supported signaling standards before substitution.
