DS160PR421 4-Channel Linear Redrivers

Texas Instruments DS160PR421 4-Channel Linear Redrivers come with an 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 the best transmit and receive equalization settings resulting in the best electrical link and lowest possible latency. Low channel-channel cross-talk, low additive jitter, and excellent return loss allow the device to become almost a passive element in the link. The device has an internal linear voltage regulator to provide a clean power supply for high-speed data paths that provides high immunity to any supply noise on the board. The Texas Instruments 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.
