STDP4020 DisplayPort receiver
The STDP4020 is a DisplayPort receiver IC for the secure reception of high-bandwidth uncompressed digital audio-video signals targeted for applications such as DTV, LCD monitor, projector, and other types of display systems. STDP4020 is a VESA DP 1.1a and eDP compliant device, implementing a single link DisplayPort input port comprising four main lanes, auxiliary channel, and HPD. In addition to the standard HBR (2.7 Gbps) and RBR (1.62 Gbps) speeds, this device supports “turbo” speed of 3.24 Gbps per lane with a total link bandwidth of 12.96 Gbps. The higher bandwidth provides unique benefits to users over other commercial DP receivers for embedded applications by offering additional margin to support higher color depth, resolution, and refresh rate. For example, STDP4020 supports FHD non-reduced blanking video (1080p 30-bit color per pixel) at 120 Hz, plus 7.1 Ch audio in two-box TV applications. The advanced equalizer built in this device offers guaranteed performance over long reach cables. The auxiliary channel in STDP4020 acts as a bidirectional communication link, supporting application-specific protocols such as MCCS, DDC, UART, IR, as well as the dedicated DisplayPort link training and device management functions.
The STDP4020 supports RGB and YCC video color formats with color depth of 12 (YCC 4:2:2 only), 10, and 8 bits. This device offers LVDS and LVTTL output interfaces configurable to map a wide range of display controller products. The Quad LVDS interface supports video signals up to 400 MHz pixel rate with flexible channel and lane swapping options. The 60-bit LVTTL output ports can be mapped to transfer video data either in two pixels per clock or single pixel per clock up to 300 MHz pixel rate. The STDP4020 also supports both compressed and uncompressed audio formats. The extracted audio signal is transferred on a digital audio output bus. This device comprises four I2S audio output ports, supporting up to 8 channel LPCM audio and a single wire SPDIF output for encoded audio. The STDP4020 features HDCP 1.3 content protection scheme with an embedded key option for secure reception of digital audio-video content. In addition, it supports the HDCP repeater function and, thus acts as an upstream receiver suitable for two-box TV and DP to HDMI/DVI converter applications.
The STDP4020 is configurable from an external host controller through I²C host interface. This device also includes general purpose inputs/outputs for controlling system components. The STDP4020 features a color space converter (RGB to YCC and YCC to RGB) for flexible interface with external video processing devices
