Texas Instruments DS110DF111 DS110DF111 Low Power Multi-Rate Two-Channel Retimer DS110DF111SQE/NOPB

The DS110DF111SQE/NOPB is a low-power, multi-rate, dual-channel retimer designed for high-speed serial data applications. It supports data rates from 8.5 to 11.3 Gbps and features integrated continuous-time linear equalization (CTLE), clock and data recovery (CDR), and a transmit driver for each channel. The device includes a self-tuning 5-tap decision feedback equalizer (DFE) that enhances signal integrity over long, lossy interconnects, achieving a bit error rate (BER) of less than 1x10^-15. The DS110DF111 operates with a single power supply of 3.3 V or 2.5 V and consumes 200 mW per channel. It offers adjustable transmit voltage output (V_OD) ranging from 600 to 1300 mVp-p and supports programmable transmit de-emphasis from 0 to -12 dB. The device is packaged in a compact 24-pin WQFN format, measuring 4.0 mm x 4.0 mm, and is suitable for applications such as front port optical interconnects, 10G/1G Ethernet, and CPRI. The operating temperature range is -40°C to 85°C, making it suitable for various environmental conditions.
