  • 1 Introduction The DS320PR810-RSC-EVM evaluation module features four DS320PR810 linear redrivers that can extend the transmission distance of a PCIe Gen-5 x16 bus. The evaluation module can directly be plugged into a PCIe slot on a server or PC motherboard using one end of the board, and paired up with a PCIe add-in card using the straddle mount connector attached to the other end of the board. 1.1 Features The DS320PR810-RSC-EVM evaluation module include
  • 2 Description 2.1 DS320PR810 5-Level I/O Control Inputs Each DS320PR810 features 5-level input pins (MODE, GAIN0, GAIN1, RX_DET, EQ0_0/ADDR0, EQ1_0/ ADDR1, EQ0_1, and EQ1_1) that are used to control the configuration of the device. These 5-level inputs use a resistor divider to help set the four valid levels to provide a wider range of control settings. Table 2-1.

  • 2.3 DS320PR810 SMBus or I2C Register Control Interface The DS320PR810 internal registers can be accessed through standard SMBus protocol. The DS320PR810 features two banks of channels, Bank 0 (Channels 0–3) and Bank 1 (Channels 4–7), each featuring a separate register set and requiring a unique SMBus slave address. The SMBus slave address pairs (one for each channel bank) are determined at power up based on the configuration of the EQ0_0/ADDR1 and EQ1_
  • 2.4 DS320PR810 Equalization Control Each channel of the DS320PR810 features a continuous-time linear equalizer (CTLE) that applies high- frequency boost and low-frequency attenuation to help equalize the frequency-dependent insertion loss effects of the passive channel. Table 2-4 shows available equalization boost through EQ control pins (EQ1_0 and EQ0_0 for channels 0–3 and EQ1_1 and EQ0_1 for channels 4–7) when in Pin Control mode (MODE = L0). Table
