Description

The SN75DP130 is a single channel DisplayPort (DP) re-driver that regenerates the DP high speed digital link. The device complies with the VESA DisplayPort Standard Version 1.2, and supports a four lane Main Link interface signaling up to HBR2 rates at 5.4Gbps per lane, and supports DP++ Dual-Mode; offering TMDS signaling for DVI and full HDMI Version 1.4a support.

The device compensates for PCB related frequency loss and switching related loss to provide the optimum DP electrical performance from source to sink. The Main Link signal inputs feature configurable equalizers with selectable boost settings. At the Main Link output, four primary levels of differential output voltage swing (VOD) and four primary levels of pre-emphasis are available, as well as a secondary level of boost adjustment, programmed through I2C, for fine-tuning the Main Link output. The device can monitor the AUX channel and automatically adjust the output signaling levels and input equalizers in response to Link Training commands. Additionally, the SN75DP130 output signal conditioning and EQ parameters are fully programmable through the I2C interface.

The SN75DP130 offers separate AUX and DDC source interfaces that connect to a single AUX sink channel. This minimizes component count when implemented with a graphics processor (GPU) comprising separate DDC and AUX interfaces. For GPUs with combined DDC/AUX, the device can operate as a FET switch to short circuit the AUX channel AC coupling caps while connected to a TMDS sink device. Other sideband circuits such as Hot Plug Detect (HPD) are optimized to reduce external components, providing a seamless connection to Intel, AMD, and NVIDIA graphics processors.

The SN75DP130 is optimized for mobile applications, and contains activity detection circuitry on the Main Link input that transitions to a low-power Output Disable mode in the absence of a valid input signal. Other low power modes are supported, including a Standby mode with typical dissipation of ~2mW when no video sink (e.g., monitor) is connected.

The device is characterized for an extended operational temperature range from 0°C to 85°C.
