SN65LVCP40RGZT

Signal Buffers, Repeaters, Splitters Overview

The SN65LVCP40RGZT is a DC to 4-Gbps dual 1:2 multiplexer/repeater/equalizer designed for backplane applications. It operates on a single 3.3-V supply and supports signaling rates up to 4 Gbps, including XAUI and GbE protocols. The device integrates two independent channels, each featuring a transmitter with a fan-out of two and a receiver with a 2:1 input multiplexer. Key electrical parameters include a data rate of 4 Gbps, an operating temperature range from -40°C to +85°C, and typical power consumption of 650 mW. It utilizes CML/LVPECL inputs and VML outputs within a 48-terminal QFN package.

Signal Buffers, Repeaters, Splitters Feature Summary

• Integrates programmable output preemphasis and selectable driver levels to counteract high-frequency transmission line losses.
• Incorporates receiver equalization to compensate for input transmission line loss and minimize deterministic jitter.
• Features selectable switch-side loopback functionality to support system testing and redundancy switching.

Signal Buffers, Repeaters, Splitters Applications

• Redundancy switching in serial interconnects
• Signal buffering for legacy backplane hardware
• Performance improvement on backplane links

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the obsolete status of this component before procurement planning. Confirm that the RGZT suffix corresponds to the tape-and-reel packaging variant. Ensure compatibility with existing PCB footprints for the 48-pin QFN package. Review the latest Texas Instruments product life cycle notices for availability constraints.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this device when signal conditioning is required for FR-4 backplane traces up to approximately 24 inches. Verify that the input signaling standards (LVDS, LVPECL, or CML) match the source equipment. Consider the 3.3-V supply requirement and thermal characteristics for the specific enclosure environment.
