DS125BR401具有均衡器和去加重功能的 中继器

the ds125br401 is an extremely lowpower, high performance multi-protocol repeater/redriver designed to support 4-lanes of sas-3/2/1, pcie gen-3/2/1, 10g-kr and other high speed interface serial protocols up to 12.5 gbps. thereceiver's continuous time linear equalizer (ctle) provides a boost of up to +30 db at 6.25 ghz (12.5 gbps) in each of its eight channels and is capable of opening an input eye that is completelyclosed due to inter symbol interference (isi) induced by interconnect medium such as 30″+ backplane traces or 8m+ copper cables, hence enabling host controllers to ensure an error free end-to-endlink. the transmitter provides a de-emphasis boost of up to –12 db and output voltage amplitude control from 700 mv to 1300 mv to allow maximum flexibility in the physical placement within theinterconnect channel.
when operating in sas-3, 10g-kr and pcie gen-3 mode, the ds125br401 transparently allows the host controller and the end point to optimize the full link and negotiate transmit equalizer coefficients.this seamless management of the link training protocol ensures guaranteed system level interoperability with minimum latency. with a low power consumption of 65 mw/channel (typ) and option toturn-off unused channels, the ds125br401 enables energy efficient system design. a single supply of 3.3v or 2.5v is required to power the device.
the programmable settings can be appliedeasily via pins, software (smbus/i2c) or loaded via an external eeprom. when operating in the eeprom mode, the configuration information is automatically loaded on power up, which eliminates the needfor an external microprocessor or software driver.
