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.
