1. Description

The STDP4020 is a DisplayPort receiver IC for the reception of secure, 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 for 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 YUV video color formats with color depth of 12 (YUV 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 330 MHz pixel rate, which

opens up possibilities for 3D applications. 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, supporting up to 8 channel LPCM audio and a single wire

S/PDIF output for encoded audio. The STDP4020 features the HDCP 1.3 content protection scheme with

an embedded key option for secure reception of digital audio-video content. In addition, it also supports

the HDCP repeater function and, thus acts as an upstream receiver suitable for two-box TV and

HDMI/DVI converter applications.

The STDP4020 is configurable from an external host controller through I2C host interface. This IC also

includes general-purpose inputs/outputs for controlling system components. The STDP4020 features a

color space converter (RGB to YUV and YUV to RGB) for flexible interface with external video

processing devices.
