TDP2004 DisplayPort 2.1 Linear Redriver

Texas Instruments TDP2004 DisplayPort 2.1 Linear Redriver is a four-channel, low-power, high-performance linear repeater or redriver designed to support DisplayPort 2.1 up to 20Gbps. The TDP2004 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. A linear output driver follows the CTLE receiver. The linear data paths of TDP2004 preserve and transmit preset signal characteristics. High bandwidth, low channel-to-channel cross-talk, low additive jitter, and excellent return loss make the device almost a passive element in the link, but with its useful equalization. The DisplayPort link training is effective through the linear redriver that becomes part of the passive channel between source Tx and sink Rx. This link training protocol transparency results in excellent electrical links and the 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 Texas Instruments TDP2004 has low AC and DC gain variation, providing consistent equalization in high-volume platform deployment.
