From the project
MS9288A based VGA / YPbPr to HDMI Converter PCB
The MS9288A is a low-cost, low-power, high performance device, which consists of HDMI Transmitter, three 10-bit video Analog-to-Digital Converters and audio encoder, which can convert VGA or YPbPr signals to HDMI, maximum conversion rate of 165MHz. MS9288A support L/R audio input.MS9288A with embedded MCU and ROM code.
