1. Description

The STDP4028 is a DisplayPort transmitter IC for the secure transmission of high-bandwidth,

uncompressed digital audio-video signals targeted for applications such as DTV, LCD monitor, docking

station, STB and other types of consumer audio-video systems. STDP4028 is VESA DP 1.1a and eDP

compliant device, implementing a single link DisplayPort output 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 transmitters for embedded

applications by offering additional margin to support higher color depth, resolution, and refresh rate. For

example, STDP4028 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 high-speed auxiliary channel in STDP4028 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 STDP4028

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 input interface 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 input ports on STDP4028 can be mapped to transfer video

data either in two pixels per clock or single pixel per clock of a chosen color depth. The STDP4028 also

supports both compressed and uncompressed audio formats.

This device comprises four I2S audio inputs, supporting up to 8 channels LPCM audio and a single wire

SPDIF input for encoded audio. The STDP4028 features HDCP 1.3 content protection scheme with an

embedded key option for secure transmission of digital audio-video content. In addition, it supports the

HDCP repeater function and, thus acts as a downstream transmitter suitable for two-box TV and

HDMI/DVI to DP converter applications. The STDP4028 is configurable from an external host through the

I2C host interface. This IC also includes general-purpose inputs/outputs for controlling system

components. The STDP4028 features a color space converter (RGB to YUV and YUV to RGB) for

flexible interface with external video processing devices.
