TI SN75DP130SSRGZR

The SN75DP130 device is a single-channel DisplayPort (DP) retimer that regenerates the DP high-speed digital link. This device complies with the VESA DisplayPort standard version 1.2 and supports a 4-lane main link interface, allowing each lane to transmit signals at the HBR2 rate of 5.4 Gbps. The device also supports the DP++ dual-mode, which provides TMDS signaling for DVI and full-size HDMI version 1.4a. The device compensates for PCB-related frequency losses and switching-related losses to provide optimal DP electrical performance between the source and receiving devices. The main link signal input features a configurable equalizer and optional boost settings. The main link output offers four primary differential output voltage swings (VOD) and four primary pre-emphasis settings. Secondary boost adjustments can be made via I²C programming to fine-tune the main link output. The device monitors the AUX channel and automatically adjusts the output signal level and input equalizer according to link negotiation commands. Additionally, the output signal conditioning and EQ parameters of the SN75DP130 are fully programmable via the I²C interface.

The SN75DP130 is optimized for mobile applications and is equipped with an activity detection circuit at the main link input, which switches to a low-power output disable mode when there is no valid input signal. The device also supports other low-power modes such as standby mode. In standby mode, if no video receiving device (e.g., a monitor) is connected, the typical power consumption is only about 2 mW. This device features an extended operating temperature range between 0°C and 85°C.

The SN75DP130 provides separate AUX and DDC source device interfaces for connecting to the AUX receiving device channels. This minimizes the number of components when used with a graphics processing unit (GPU) that includes separate DDC and AUX interfaces. For GPUs with a combined DDC/AUX, the device can short-circuit the AUX channel AC coupling capacitor as a FET switch when connected to a TMDS receiving device. Other sideband circuits such as hot-plug detect (HPD) have been optimized to reduce external components and enable seamless connection with Intel, AMD, and NVIDIA graphics processors.
