The TDP20MB421 is a 4-channel linear redriver with an integrated 2:1 MUX. The low-power, high-performance linear redriver is designed to support DisplayPort 2.1 up to 20Gbps.
The TDP20MB421 receivers deploy continuous time linear equalizers (CTLE) to provide a programmable high-frequency boost. The equalizer opens an input eye that is completely closed due to inter-symbol interference (ISI) induced by an interconnect medium, such as PCB traces. A CTLE receiver is followed by a linear output driver. The linear data paths of TDP20MB421 preserve the characteristics of the transmit preset. High bandwidth, low channel-to-channel crosstalk, low additive jitter, and excellent return loss make the device almost a passive element in the link. The DisplayPort link training is effective through the device as the device becomes part of the passive channel between the source Tx and sink Rx. The device transparency in the link-training protocol results in the best electrical link and lowest possible latency. The data path of the device uses an internally regulated power rail that provides high immunity to supply noise on the board.
The TDP20MB421 implements high-speed testing during production for reliable, high-volume manufacturing. The device also has low AC and DC gain variation, providing consistent equalization in high-volume platform deployment.
