3 Description
The DS100BR210 is an extremely low power, high
performance repeater designed to support serial links
with data rates up to 10.3 Gbps. The DS100BR210
pinout is configured as two unidirectional channels.
The DS100BR210 inputs feature a powerful 4-stage
continuous time linear equalizer (CTLE) to provide a
boost of up to +36 dB at 5 GHz and open an input
eye that is completely closed due to inter-symbol
interference (ISI) induced by the interconnect
mediums such as board traces or twin-axial copper
cables. The transmitter features a programmable
output de-emphasis driver with up to -12 dB and can
drive output voltage levels from 700 mVp-p to 1300
mVp-p.
When configured as a 10G-KR repeater, the
DS100BR210 allows the KR host and the end point to
optimize the full link by adjusting transmit and receive
equalizer coefficients using back-channel
communication techniques specified by the 802.3ap
Ethernet standard.
The programmable settings can be applied via pin
control, SMBus protocol, or an external EEPROM. In
the EEPROM mode, the configuration information is
automatically loaded on power up, thereby eliminating
the need for an external microprocessor or software
driver.
