PI6C49CB01Q3WEX

Clock Buffers, Drivers Overview

The PI6C49CB01Q3WEX is a 1-to-1 Differential-to-LVCMOS/LVTTL Translator High Performance Buffer manufactured by Diodes Incorporated. It accepts differential inputs including LVPECL, LVDS, LVHSTL, SSTL, and HCSL, converting them to a single-ended LVCMOS or LVTTL output. The device operates on a supply voltage of 2.375 V to 3.465 V with an output frequency up to 360 MHz. Propagation delay ranges from 1.6 ns to 2.5 ns depending on the supply voltage. It is AEC-Q100 qualified for Grade 3 automotive applications (-40°C to +85°C) and housed in an 8-pin SOIC package.

Clock Buffers, Drivers Feature Summary

• AEC-Q100 Qualified Automotive Grade 3 compliant (-40°C to +85°C)
• Low additive phase jitter: 0.15 ps RMS (typical) at 3.3V, 125MHz

Clock Buffers, Drivers Applications

• Automotive clock distribution systems requiring specific change control
• Converting differential clock signals to single-ended logic levels
• Applications with limited board space utilizing the 8-lead SOIC footprint

Clock Buffers, Drivers Procurement Notes

Verify that the ordering suffix '3' corresponds to the required -40°C to +85°C temperature range. Confirm the 'WEX' suffix indicates the 8-pin Wide SOIC package and Tape/Reel packaging format. Ensure compliance with RoHS and Halogen-free requirements as specified in the datasheet notes.

Clock Buffers, Drivers Selection Notes

Select this component when a single-ended LVCMOS or LVTTL output is needed from various differential clock sources. The 360 MHz maximum frequency supports high-speed digital interfaces. Consider the 500 ps part-to-part skew specification for multi-device synchronization requirements within the system design.

Clock Buffers, Drivers Part Context

This part belongs to the PI6C49CB01Q family of automotive-qualified buffers. The '3' suffix specifically denotes the Grade 3 temperature rating (-40°C to +85°C), distinguishing it from the Grade 2 variant which supports up to +105°C. Both variants share identical electrical characteristics but differ in thermal qualification.

Clock Buffers, Drivers Replacement Considerations

The PI6C49CB01Q2WEX serves as a direct functional substitute if the application requires the extended temperature range of -40°C to +105°C (Automotive Grade 2). Electrical parameters remain consistent between the two variants.
