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.
