DS110DF111SQE/NOPB

The DS110DF111SQE/NOPB from Texas Instruments is a high-performance, dual-channel retimer with integrated signal conditioning capabilities. This device is engineered to enhance signal integrity in demanding applications, supporting multi-rate operation from 8.5 to 11.3 Gbps.

Key electrical features include AC-coupling and CML input compatibility, along with support for protocols such as 10G-SR/LR, General Purpose, and Infiniband. The retimer incorporates an input Continuous-Time Linear Equalizer (CTLE) with up to 34 dB boost at 5.65 GHz, a clock and data recovery (CDR) circuit, and a transmit driver on each channel. It also features a self-tuning 5-tap Decision Feedback Equalizer (DFE) for improved signal equalization.

Designed for surface mount, the DS110DF111SQE/NOPB comes in a compact 24-WQFN (4x4 mm) package. It operates within a temperature range of -40°C to 85°C and is compatible with single 3.3-V or 2.5-V power supplies. Configuration can be managed via SMBus, EEPROM, or pin-based settings. The low power consumption of 200 mW per channel makes it suitable for power-sensitive designs.

This retimer is ideal for applications requiring robust signal integrity over long traces or through noisy environments. Its integrated features simplify system design by reducing the need for external components for signal conditioning.
