3 General Description
NCS8828 is a low-cost, low-power semiconductor device that consists of HDMI receiver,three separate 9-bit video Digital-to-Analog Converters (DACs) and audio encoder, which can convert HDMI signals into YPbPr outputs at a maximum conversion rate of 200MHz with DAC audio output.
The HDMI Receiver integrated is compliant with HDMI 1.4a and support HDCP 1.4 specifications with internal HDCP key.
The DACs are based on current source architecture. And the YPbPr output meet VESA VSIS v1r2 clock jitter target. With sophisticated MCU and the Boot ROM embedded,NCS8828 support auto-boot and EDID buffer. Take the advantage of Firmware auto loaded from the embedded Boot ROM, NCS8828 can support HDMI input detection, DAC connection detection and determine to enter into Power saving mode automatically.
NCS8828 is typically required to support WUXGA (1920x1200) and above at 60Hz frame rate and Minimum support to XGA (1024*768@60Hz) fail safe mode.
Thanks to our proprietary scaling algorithm, NCS8828 provides high picture quality. All the functions pack into a small 4mm*4mmQFN32 package which saves the precious space in mobile devices.
