Designed to support 1-lane carrying high-speed interface up to 12.5Gbps, theDS125BR111 is an extremely low-power high-performance repeater / redriverfrom Texas Instruments (TI).
The receiver’s continuous time linear equalizer (CTLE) provides a boost of3-10dB at 6GHz in each channel. When operating in SAS-3 or PCIe Gen-3applications, the DS125BR111 preserves transmit signal characteristicsallowing the host controller and the end point to negotiate transmitequalizer coefficients. Transparency to the link training protocol maximizesthe flexibility of the physical placement of the device within theinterconnect and improves overall channel performance.
The programmable settings can be applied easily via pins, software (SMBus orI2C), or loaded via an external EEPROM. In EEPROM mode, the configurationinformation is automatically loaded on power up, which eliminates the needfor an external microprocessor or software driver, says the company.
