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.
