PI6C49CB01Q2WEX

Clock Buffers, Drivers Overview

The PI6C49CB01Q2WEX is a 1-to-1 differential-to-LVCMOS/LVTTL translator 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 ranging from 2.375 V to 3.465 V and supports maximum output frequencies up to 360 MHz. Propagation delay is specified at a maximum of 2.5 ns for 2.5 V operation and 2.0 ns for 3.3 V operation. It features part-to-part skew of 500 ps maximum and additive phase jitter as low as 0.09 ps RMS. The component is housed in an 8-pin SOIC (W) package and is qualified under AEC-Q100 standards.

Clock Buffers, Drivers Feature Summary

• Differential input compatibility with LVPECL, LVDS, LVHSTL, SSTL, and HCSL levels
• Single-ended LVCMOS/LVTTL output capability
• AEC-Q100 Grade 2 qualification for automotive applications (-40°C to 105°C)
• Low additive phase jitter (0.09 ps RMS typical at 3.3V)

Clock Buffers, Drivers Applications

• Automotive electronic control units requiring clock translation
• Systems with limited board space utilizing the 8-lead SOIC footprint
• Interfaces between differential clock sources and single-ended logic loads

Clock Buffers, Drivers Procurement Notes

Verify that the ordering suffix '2' corresponds to the Automotive Grade 2 temperature range (-40°C to 105°C). Confirm the 'WEX' suffix indicates the 8-pin SOIC package and Tape/Reel packaging format. Ensure compliance with RoHS and Halogen-free requirements if specified for the target assembly process.

Clock Buffers, Drivers Selection Notes

Select this component when a single differential input must be translated to a single LVCMOS or LVTTL output. The PI6C49CB01Q2WEX is suitable for designs requiring AEC-Q100 Grade 2 qualification. For Grade 3 qualification (-40°C to 85°C), the PI6C49CB01Q3WEX variant should be considered instead.

Clock Buffers, Drivers Part Context

This part belongs to the PI6C49CB01Q family of differential translators. The specific suffix '2' denotes the Automotive Grade 2 temperature rating. Other variants in the series include the Q3 suffix for Grade 3 ratings. The device is distinct from multi-output buffers like the PI6C49CB02Q series.

Clock Buffers, Drivers Replacement Considerations

The PI6C49CB01Q3WEX serves as a direct replacement for applications requiring the lower Automotive Grade 3 temperature range (-40°C to 85°C). Verify thermal requirements before substituting.
