STDP4028 Reference Design 2 – LVDS 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 RD2-4028 is a low cost compact four-layer board that includes necessary interfaces and features to fully demonstrate the STDP4028 transmitter functionalities.
This reference design meets the following:
- Stand-alone operation: Includes necessary firmware (either IROM or external SPI) to work independently; this means the intended functionalities are performed without depending on external controller (Host).
- Slave configuration: Provision to configure the device by an external Host controller through the Host Interface to I2C (most likely when no SPI Flash is used).
