3 Description
The TDP2004-Q1 is a four-channel low-power highperformance
linear repeater or redriver designed
to support DisplayPort 2.1 up to 20Gbps and AC
coupled HDMI2.1 Source up to 12Gbps.
The TDP2004-Q1 receivers deploy continuous time
linear equalizers (CTLE) to provide a programmable
high-frequency boost. The equalizer can open an
input eye that is completely closed due to intersymbol
interference (ISI) induced by an interconnect
medium, such as PCB traces or cables. The linear
data-paths of TDP2004-Q1 preserve transmit preset
signal characteristics. High bandwidth, low channelto-
channel cross-talk, low additive jitter and excellent
return loss makes the device almost a passive
element in the link, but with useful equalization. The
DisplayPort link training is effective through the linear
redriver that becomes part of the passive channel in
between source Tx and sink Rx. This transparency in
the link training protocol results in optimum electrical
link and lowest possible latency. The data-path of the
device uses an internally regulated power rail that
provides high immunity to any supply noise on the
board.
The device also has low AC and DC gain variation
providing consistent equalization in high volume
platform deployment.
