TLK1101ERGPR

Specialized Overview

The TLK1101ERGPR is a high-speed cable and printed circuit board equalizer manufactured by Texas Instruments. It operates at data rates up to 11.3 Gbps, designed to compensate for signal attenuation in copper interconnects. The device utilizes a single-supply voltage configuration ranging from 2.97 V to 3.63 V. It is housed in a compact 28-lead QFN package with dimensions of 4 mm by 4 mm. The component supports an operating temperature range from -40°C to +85°C, ensuring reliability in industrial environments. Power consumption is managed through integrated biasing circuits.

Specialized Feature Summary

• Provides active equalization for high-speed serial signals over lossy transmission lines
• Supports data rates up to 11.3 Gbps for backplane and cable applications
• Integrates automatic gain control to maintain signal integrity across varying channel losses

Specialized Applications

• Backplane interconnects in telecommunications equipment
