SN65LVCP40RGZ

Signal Buffers, Repeaters, Splitters Overview

The SN65LVCP40RGZ is a dual 1:2 multiplexer, repeater, and equalizer designed for serial backplane applications up to 4 Gbps. It operates from a single 3.3-V supply within a -40°C to 85°C temperature range. The device features selectable receiver equalization and programmable output preemphasis to counteract transmission line losses. Each channel includes a transmitter with a fan-out of two and a receiver with a 2:1 input multiplexer. It supports CML, LVDS, and LVPECL inputs and provides VML outputs with integrated 100-Ω termination.

Signal Buffers, Repeaters, Splitters Feature Summary

• Integrates dual channels combining 1:2 buffers and 2:1 multiplexers for signal conditioning and redundancy switching.
• Provides selectable receiver equalization and four levels of programmable output preemphasis to compensate for high-frequency transmission line losses.
• Features on-chip 100-Ω differential termination and self-biasing networks that eliminate the need for external components.

Signal Buffers, Repeaters, Splitters Applications

• Redundancy switching in serial interconnects
• Signal buffering and performance improvement on legacy backplane hardware
• XAUI protocol implementation

Signal Buffers, Repeaters, Splitters Procurement Notes
