Ultra Low Power, 8-Channel Repeater for Data-rates up to
10.3 Gbps
General Description
The DS100KR800 is an extremely low power, high perfor-
mance repeater designed to support 8 channel (uni-direction-
al) 10G-KR and other high speed interface serial protocols up
to 10.3 Gbps. The receiver's continuous time linear equalizer
(CTLE) provides a boost of up to +36 dB at 5 GHz (10.3125
Gbps) in each of its eight channels and is capable of opening
an input eye that is completely closed due to inter symbol in-
terference (ISI) induced by interconnect medium such as long
backplanes or cables, hence enabling host controllers to en-
sure an error free end-to-end link. The transmitter provides a
de-emphasis boost of up to -12 dB and output voltage ampli-
tude control from 700 mV to 1300 mV to allow maximum
flexibility in the physical placement within the interconnect
channel.
When operating in 10G-KR mode, the DS100KR800 trans-
parently allows the host controller and the end point to opti-
mize the full link and negotiate transmit equalizer coefficients
as defined in the 802.3ap standard. This seamless manage-
ment of the link training protocol ensures guaranteed system
level interoperability with minimum latency.
With a low power consumption of 65 mW/channel (typ) and
option to turn-off unused channels, the DS100KR800 enables
energy efficient system design. A single supply of 3.3v or 2.5v
is required to power the device.
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.
