8P34S1204NLGI/W

Clock Buffers, Drivers Overview

The 8P34S1204NLGI/W is a high-performance differential LVDS fanout buffer manufactured by Renesas Electronics Corporation. It features a 2:4 input-to-output ratio, supporting two selectable differential clock inputs and four low-skew outputs. The device operates from dual supply voltages of 1.71V to 1.89V or 2.1V to 2.7V, accommodating LVDS and CML input levels. Encased in a 16-VFQFN package with exposed pad, it supports maximum frequencies up to 1.2 GHz. Key electrical characteristics include a typical output skew of 10ps and a maximum propagation delay of 400ps, ensuring precise timing for high-speed clock distribution.

Clock Buffers, Drivers Procurement Notes

Verify the suffix 'W' against official documentation, as standard listings often cite 'NLGI'. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) prior to ordering. Check for specific packaging variations such as tray quantities versus reel options, as these may differ based on the exact suffix configuration.

Clock Buffers, Drivers Selection Notes

Select this component when low additive phase jitter and guaranteed part-to-part skew are required. Ensure the design accommodates the 16-VFQFN thermal requirements. Verify that the system power rails align with the specified 1.8V or 2.5V operating ranges. Consider the 1.2 GHz maximum frequency limit relative to the target application speed.
