Ultra Low Power 10.3 Gbps 2-Channel Repeaters with Input
Equalization and Output De-Emphasis
General Description
The DS100BR111A is an extremely low power, high perfor-
mance dual-channel repeater for serial links with data rates
up to 10.3 Gbps. The DS100BR210A features one bidirec-
tional lane (one transmit, one receive channel).
The DS100BR111A features a powerful continuous time lin-
ear 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 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 600 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 oper-
ating 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 National's PowerWise family of energy efficient de-
vices, the DS100BR111A consumes just 65 mW/channel
(typical), and allow the option to turn-off unused channels.
This ultra low power consumption eliminates the need for ex-
ternal heat sinks and simplifies thermal management in active
cable applications.
