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.
