DS125BR800 的說明
The DS125BR800 device is an extremely low-power high-performance multiprotocol
repeater/redriver designed to support eight channels of PCIe Gen-3/2/1, 10G-KR, and other
high-speed interface serial protocols up to 12.5 Gbps. The continuous time linear equalizer (CTLE)
of the receiver provides a boost of up to
+30 dB at 6.25 GHz (12.5 Gbps) in each of its eight channels and can open an input eye that
is completely closed due to intersymbol interference (ISI) induced by interconnect medium such as
30in+ backplane traces or 8m+ copper cables, hence enabling host controllers to ensure an
error-free end-to-end link. 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 the interconnect channel.
When operating in 10G-KR and PCIe Gen-3 mode, the DS125BR800 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 system-level interoperability with minimum latency. With a low power consumption of 65 mW per channel (typical) and option to turn off unused channels, the DS125BR800 enables energy efficient system design. A single supply of 3.3 V or 2.5 V is required to power the device.
The programmable settings can be applied easily through pins, software (SMBus or I2C) or loaded through an external EEPROM. When operating in the EEPROM mode, the configuration information is automatically loaded on power up, which eliminates the need for an external microprocessor or software driver.
