8P34S2102NLGI/W

Clock Buffers, Drivers Overview

The 8P34S2102NLGI/W is a high-performance, low-power differential dual 1:2 LVDS fanout buffer manufactured by Renesas Electronics. Designed for the distribution of 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 operates from a 1.8V or 2.5V power supply. It accepts LVDS, LVPECL, and single-ended LVCMOS inputs, with a maximum input frequency of 2.0 GHz. Outputs are selectable at 350mV or 500mV amplitudes. Packaged in a 16-lead VFQFPN (3x3mm) with an exposed pad, it functions within a temperature range of -40°C to +85°C.

Clock Buffers, Drivers Feature Summary

• Dual independent 1:2 LVDS output channels with high isolation to minimize noise coupling
• Maximum input frequency of 2.0 GHz with typical output skew of 30ps and output bank skew of 5ps
• Low additive phase jitter (typical 40fs RMS at fREF = 156.25MHz)
• Integrated bias voltage references facilitate easy interfacing of AC-coupled signals

Clock Buffers, Drivers Applications

• High-speed clock distribution systems requiring well-defined performance and repeatability
• Fanout of high-frequency, very low additive phase-noise clock and data signals
• Applications demanding low skew and matched propagation delay across channels

Clock Buffers, Drivers Procurement Notes

Verify the suffix /W against official documentation to confirm specific packaging or environmental compliance details, as standard listings may vary. Confirm RoHS status and moisture sensitivity level (MSL 3) requirements for your assembly process. Ensure the 16-VFQFPN package dimensions match your PCB footprint design constraints.

Clock Buffers, Drivers Selection Notes

Select this component when dual-channel LVDS buffering with low skew is required. It supports both 1.8V and 2.5V supply voltages, offering flexibility for different system architectures. The device handles multiple input formats including LVDS, LVPECL, and LVCMOS, simplifying interface design for mixed-signal environments.

Clock Buffers, Drivers Part Context

The 8P34S2102 belongs to the Renesas 8P34S series of clock buffers.
