3 Description

The SN75DP130 device 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 4-lane Main Link interface signaling up to HBR2 rates at 5.4 Gbps per lane. This device also 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. 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.

5 Description (continued)

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 approximately 2 mW when no video sink (for example, monitor) is connected.

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

The SN75DP130 offers separate AUX and DDC source interfaces that connect to one 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.

AUX CHANNEL AND DDC DATA TERMINALS
AUX_SRCn 29 I/O
(100-Ω diff)		 Source Side Bidirectional DisplayPort Auxiliary Data Channel. If the AUX_SNK channel is used for monitoring only, these signals are not used and may be left open.

(100-Ω diff)		 Sink Side Bidirectional DisplayPort Auxiliary Data Channel.
AUX_SNKp 28
SDA_DDC 34 I/O Bidirectional I2C Display Data Channel (DDC) for TMDS mode. These signals may be used together with AUX_SNK to form a FET switch to short-circuit the AC coupling capacitors during TMDS operation in a DP++ Dual-Mode configuration. These terminals include integrated 60-kΩ pullup resistors
SCL_DDC 33
HPD, CAD, AND CONTROL TERMINALS
HPD_SRC 9 O Hot Plug Detect Output to the DisplayPort Source.
HPD_SNK 11 I DisplayPort Hot Plug Detect Input from Sink. This device input is 5-V tolerant.
Note: Pull this input high during compliance testing or use I2C control interface to go into compliance test mode and control HPD_SNK and HPD_SRC by software.
CAD_SRC 8 O DP Cable Adapter Detect Output. This output typically drives the GPU CAD input.
CAD_SNK 10 I DisplayPort Cable Adapter Detect Input. This input tolerates a 5-V supply with a supply impedance higher than 90kΩ. A device internal zener diode limits the input voltage to 3.3 V.
An external 1MΩ resistor to GND is recommended. This terminal is used to select DP mode or TMDS mode in a DP++ Dual-Mode application.
SCL_CTL 4 I/O Bidirectional I2C interface to configure the SN75DP130. This interface is active independent of the EN input but inactive when RSTN is low.
SDA_CTL 5
RSTN 35 I Active Low Device Reset. This input includes a 150-kΩ resistor to the VDDD core supply. An external capacitor to GND is recommended on the RSTN input to provide a power-up delay (see the VIL and VIH specifications in Recommended Operating Conditions).
This signal is used to place the SN75DP130 into Shutdown mode for the lowest power consumption. When the RSTN input is asserted, all outputs (excluding HPD_SRC and CAD_SRC) are high-impedance, and inputs (excluding HPD_SNK and CAD_SNK) are ignored; all I2C and DPCD registers are reset to their default values.
At power up, the RSTN input must not be de-asserted until the VCC and VDDD supplies have reached at least the minimum recommended supply voltage level (see Figure 34 for timing requirements).
EN 26 I Device Enable. This input incorporates an internal pullup of 200 kΩ.
ADDR_EQ 3 3-level Input I2C Target Address Select and EQ Configuration Input. If the I2C bus is used, this input setting selects the I2C target address, as described in Figure 19. This input also configures the input EQ to the device, as described in Table 3.
