3 Description

The TDP2004-Q1 is a four-channel low-power high-

performance 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 inter-

symbol 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 channel-

to-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.
