STDP4028 Reference Design 1 – DVI to DisplayPort
The STDP4028 is an integrated circuit featuring a four lane DisplayPort transmitter, quad LVDS /LVTTL receiver with I2S, and SPDIF audio inputs for digital audio-video conversion application. This device also includes SPI interface, I2C Slave (Host Interface), I2C Master Interface, UART (GProbe) interface, and general-purpose IO pins. The RD1-4028 is a low cost compact four-layer board that includes necessary interfaces and features to fully demonstrate the STDP4028 transmitter functionalities. The RD1-4028 board includes discrete TMDS receiver chips, converting DVI signal into LVTTL input for STDP4028. This board is capable of handling both single link and dual link DVI input signals supporting video resolution from 640 x 480 up to 2560 x 1600. The RD1-4028 also features digital audio inputs SPIDIF and I2S up to 8 Ch.
