12-Bit 1-Channel Video DAC PHY

Innosilicon Video DAC IP is designed for transmitting video signal from a video source device to a display device, which could be used for many analog video interfaces, such as Composite (CVBS), S-Video (Y/C) and Component (YPrPb and RGB) video interfaces.
Innosilicon Video DAC IP consists of the digital logic and the physical layer. The digital logic receives the video and clock signals from controller. It outputs these data to physical layer for further process. The physical layer contains one or multiple current-steering DACs and bias circuit. Each DAC receives 10-bit parallel input data and converts the digital data to analog current output. The output current is programmable and maximum output current is 40mA, which results in a 1.5V voltage swing on typical 37.5Ω resistance load (double 75Ω termination). The update rate is up to 300MHz. The bias circuit generates voltage and current reference.
Innosilicon Video DAC IP offers reliable implementation for analog video interface, which can be integrated in the SOC used in multimedia device.
