3 Description
The DS100BR111A is an extremely low power, high
performance repeater designed to support serial links
with data rates up to 10.3 Gbps. The DS100BR111A
pinout is configured as one bidirectional lane (one
transmit, one receive channel). The DS100BR111A
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 600 mVp-p to 1200 mVp-p.
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. The DS100BR111A consumes just 65
mW/channel (typical), and allows the option to turn off
unused channels. This ultra low power consumption
eliminates the need for external heat sinks and
simplifies thermal management in active cable
applications.
