GENERAL DESCRIPTION
The STDP4028 is a LVDS or RGB (LVTTL) to DisplayPort converter targeted for embedded and external
display applications in mobile PC, LCD monitor, projector etc. This device has a LVDS or LVTTL configurable
input port offering higher flexibility for designs that requires interfacing with FPGAs or display controller SoCs.
STDP4028 features a dual mode receiver that receives either quad LVDS input signal with a maximum pixel
rate of 400MHz or a 60-bit LVTTL signal with a maximum pixel rate of 330MHz. The DisplayPort output
interface has 4 main lanes, AUX CH and HPD with a total link bandwidth of 10.8Gbps. Besides the standard
HBR an RBR link rate, it supports turbo link rate (3.24Gbps) for video resolutions up to 1080P 120Hz 3D
timings with expanded horizontal blanking. It provides seamless video color space conversion between RGB
and YCbCr color formats supporting up to 10-bit per color. This device has four I2S and a single wire SPDIF
audio input port handling up to 8Ch LPCM or any compressed audio formats.
The STDP4028 provides HDCP 1.3 content protection on the DisplayPort output interface and functions as
HDCP repeater functionality for secure transmission of protected AV content. It also supports the eDP
authentication option ASSR (Alternative Scrambler Seed Reset) for embedded applications. This device is
available in 164 LFBGA 12mm x 12mm package.
