DESCRIPTION
The DS100KR401 is an extremely low power, high
performance repeater designed to support 4 lane (bi-
directional) 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 interference (ISI) induced by interconnect
medium such as long backplanes or cables, hence
enabling host controllers to ensure an error free end-
to-end link. The transmitter provides a de-emphasis
boost of up to -12 dB and output voltage amplitude
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 DS100KR401
transparently allows the host controller and the end
point to optimize the full link and negotiate transmit
equalizer coefficients as defined in the 802.3ap
standard. This seamless management 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
DS100KR401 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 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.
