3 Description

The DS125BR111 is an extremely low power high

performance repeater/redriver designed to support 1- lane carrying high speed interface up to 12.5 Gbps.

The receiver's continuous time linear equalizer

(CTLE) provides a boost of 3-10 dB at 6 GHz in each

channel. When operating in SAS-3 or PCIe Gen-3 applications, the DS125BR111 preserves transmit

signal characteristics allowing the host controller and

the end point to negotiate transmit equalizer

coefficients. Transparency to the link training protocol

maximizes the flexibility of the physical placement of the device within the interconnect and improves

overall channel performance.

The programmable settings can be applied easily via

pins, software (SMBus or I2C), or loaded via an

external EEPROM. In EEPROM mode, the

configuration information is automatically loaded on

power up, which eliminates the need for an external

microprocessor or software driver.
