8P34S2102NLGI

Clock Buffers, Drivers Overview

The 8P34S2102NLGI is a high-performance, low-power differential dual 1:2 LVDS fanout buffer manufactured by Renesas Electronics. Designed for distributing high-frequency, very low additive phase-noise clock and data signals, it features two independent buffer channels with matched AC characteristics. The device supports fail-safe operation and accepts LVDS, LVPECL, and single-ended LVCMOS inputs on both differential CLKA/nCLKA and CLKB/nCLKB pins. It operates from a 1.8V or 2.5V supply voltage and is housed in a 16-lead VFQFPN package.

Clock Buffers, Drivers Feature Summary

• Dual 1:2 low skew, low additive jitter LVDS fanout buffers
• High isolation between channels minimizes noise coupling
• Matched propagation delay and output-to-output skew characteristics
• Low additive phase jitter (RMS: 40fs typical at fREF = 156.25MHz)

Clock Buffers, Drivers Applications

• Fanout of high-frequency clock signals
• Distribution of very low additive phase-noise data signals
• Clock distribution applications demanding well-defined performance

Clock Buffers, Drivers Procurement Notes
