3 Description
The DS100BR111 is an extremely low power, high
performance repeater designed to support serial links
with data rates up to 10.3 Gbps. The DS100BR111
pinout is configured as one bidirectional lane (one
transmit, one receive channel). The DS100BR111
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
DS100BR111 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.
