DS160PR822数据手册集成电路（IC）的信号缓冲器、中继器、分离器规格书PDF

描述 Description

The DS160PR822 is an eight channel low-power high-performance linear redriver designed to support PCIe 4.0 and Ultra Path Interface (UPI) 2.0 up to 16 Gbps. The device is a protocol agnostic linear redriver that can operate for many differential interfaces.

The DS160PR822 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 datapaths that provides high immunity to any supply noise on the board.

The DS160PR822 implements high speed testing during production for reliable high volume manufacturing. The device also has low AC and DC gain variation providing consistant equalization in high volume platform deployment.
