DESCRIPTION
The DS64BR111 is an extremely low power, high
performance dual-channel repeater for serial links
with data rates up to 6.4 Gbps. The DS64BR111
pinout is configured as one bidirectional lane (one
transmit, one receive channel).
The DS64BR111 features a powerful 4-stage
continuous time linear equalizer (CTLE) to provide a
boost of up to +25 dB at 3.2 GHz and open an input
eye that is completely closed due to inter-symbol
interference (ISI) induced by the interconnect
mediums such as an FR-4 backplane or AWG-30
cables. The transmitter features a programmable
output de-emphasis driver with up to -12 dB and
allows amplitude voltage levels to be selected from
700 mVp-p to 1200 mVp-p to suit multiple application
scenarios.
The programmable settings can be applied via pin
settings, SMBus (I2C) protocol or an external
EEPROM. When operating in the EEPROM mode,
the configuration information is automatically loaded
on power up – This eliminates the need for an
external microprocessor or software driver.
Part of TI's PowerWise family of energy efficient
devices, the DS64BR111 consumes just 65
mW/channel (typical), and allow 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.
