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.
