Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix '2' corresponds to the Automotive Grade 2 temperature rating (-40°C to +105°C). Confirm the 'WEX' suffix indicates the 8-pin Wide SOIC package and Tape/Reel packaging format. Ensure compatibility with IATF16949:2016 certified manufacturing facilities if PPAP capability is required for the specific application.

Clock Buffers, Drivers Selection Notes

Select this component when a low skew fanout buffer is needed for automotive applications requiring AEC-Q100 qualification. Choose between the Q2 (Grade 2, -40 to 105°C) and Q3 (Grade 3, -40 to 85°C) variants based on thermal requirements. Ensure the system operates within the specified 2.375V to 3.465V supply voltage range for both VDD and VDDO pins.

Clock Buffers, Drivers Part Context

This part belongs to the PI6C49CB02Q family of automotive clock buffers. It is functionally similar to the PI6C49CB02Q3WEX but differs in the operating temperature grade. The 'Q' in the model number denotes automotive compliance, while the suffix '2' specifies the extended temperature range compared to the '3' variant.

Clock Buffers, Drivers Replacement Considerations

The PI6C49CB02Q3WEX is a direct pin-compatible alternative offering the same electrical characteristics but rated for Automotive Grade 3 (-40°C to +85°C). Verify that the lower temperature limit of the replacement meets the environmental requirements of the target application.
