TLK4211EARGTT

Specialized Overview

The TLK4211EARGTT is a high-speed limiting equalizer manufactured by Texas Instruments, designed for digital links operating at data rates up to 4.25 Gbps. It provides a fixed high-frequency boost of 12 dB at 2.1 GHz and operates on a single 3.3-V supply. The device features a 100-Ω differential input termination and CML outputs with 50-Ω back-termination. Input sensitivity reaches 200 mVp-p, while the dynamic range supports signals up to 2000 mVp-p. It includes offset cancellation, output disable, and polarity select functions. Characterized for operation from -40°C to +85°C, it is housed in a 16-pin QFN package.
