PI6C49CB04AQ3WEX

Clock Buffers, Drivers Overview

The PI6C49CB04AQ3WEX is an automotive-qualified, low skew clock buffer manufactured by Diodes Incorporated. It features a single input and four outputs packaged in an 8-pin SOIC (150mil Wide). The device operates within a supply voltage range of 1.425 V to 3.6 V and supports output frequencies up to 200 MHz at 2.5 V or 3.3 V. It provides an output-to-output skew of ±250 ps and includes an Output Enable pin for tri-stating outputs. Qualified under AEC-Q100 standards, it functions across temperature ranges of -40°C to 85°C (Grade 3) and -40°C to 105°C (Grade 2).

Clock Buffers, Drivers Feature Summary

• AEC-Q100 qualified with Automotive Grade 3 (-40 to 85 °C) and Grade 2 (-40 to 105 °C) options.
• Low skew performance with typical output-to-output skew of ±250 ps.
• Supports operating voltages from 1.425 V to 3.6 V with 3.6 V tolerant inputs.
• Packaged in an 8-pin SOIC (150mil Wide) surface-mount package.

Clock Buffers, Drivers Applications

• Automotive infotainment systems requiring precise clock distribution.
• ADAS modules needing low jitter clock buffering.
• Vehicle telematics units utilizing multiple clock domains.

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix '3' indicates the Automotive Grade 3 temperature range (-40 to 85 °C), distinct from the Grade 2 variant. Confirm RoHS compliance and lead-free status as per manufacturer specifications. Ensure packaging details match the required tape and reel quantities for automated assembly processes.

Clock Buffers, Drivers Selection Notes

Select this component when a 1:4 fanout buffer with low skew is required for automotive applications. Ensure the system power supply falls within the 1.425 V to 3.6 V range. Consider the thermal resistance characteristics if high ambient temperatures are expected, particularly for Grade 2 operation up to 105 °C.

Clock Buffers, Drivers Part Context

This part belongs to the PI6C49CB04AQ family of low skew clock buffers. The '3' suffix specifically denotes the Automotive Grade 3 temperature rating (-40 to 85 °C), while the '2' suffix corresponds to Grade 2 (-40 to 105 °C). Both variants share identical electrical characteristics but differ in their specified operating temperature limits.

Clock Buffers, Drivers Replacement Considerations

PI6C49CB04AQ2WEX offers the same electrical specifications but supports an extended temperature range up to 105 °C (Automotive Grade 2).
