DS160PR421中文资料具有集成式 2:1 多路复用器的 PCIe® 4.0、16Gbps、4 通道线性转接驱动器数据手册TI规格书

描述 Description

The DS160PR421 is four channel linear redrivers with integrated multiplexer (mux). The low-power high-performance linear redriver is designed to support PCIe 4.0 and other interfaces.

The DS160PR421 receivers deploy continuous time linear equalizers (CTLE) to provide a 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 and cables. The linear redriver along with the passive channel as a whole get link trained for best transmit and receive equalization settings resulting in best electrical link and lowest possible latency. Low channel-channel cross-talk, low additive jitter and excellent return loss allows the device to become almost a passive element in the link. The devices has internal linear voltage regulator to provide clean power supply for high speed data paths that provides high immunity to any supply noise on the board.

The DS160PR421 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.
