DS64BR401SQE Description

Short technical summary and product information.

The DS64BR401SQE from Texas Instruments is a quad lane bi-directional signal conditioning repeater supporting data rates up to 6.4 Gbps. It is suitable for SATA/SAS and other high-speed bus applications, operating at 6.0/3.0/1.5 Gbps.

This redriver features adjustable receive equalization up to +33 dB gain and adjustable transmit de-emphasis up to -12 dB. It also supports adjustable transmit VOD from 600 mVp-p to 1200 mVp-p. The device offers low power consumption at 100 mW per channel and can be programmed via pin selection or an SMBus interface.

Packaged in a 54-pin WQFN (10 mm x 5.5 mm), the DS64BR401SQE operates within a temperature range of -10°C to 85°C. It has an HBM ESD rating of over 6 kV and is compatible with 3.3V LVCMOS for SMBus interface.

Key functionalities include signal conditioning on input and output for extended reach, automatic de-emphasis scaling based on rate detect, and adjustable electrical IDLE detect threshold. It also supports SATA/SAS OOB signal pass-through with minimal envelope distortion.
