3 General Description

     NCS8823 is a low-power and high performance Type-C Alt Mode 1.2 to VGA converter, designed to connect a USB Type-C source to a VGA sink.

     The NCS8823 integrates a DP1.2 compliant receiver, and a high-speed triplechannel video DAC. Also, two CC controllers are included for CC communication to implement DP Alt Mode and power delivery function, one for upstream Type-C port and another for downstream
port.

     Two digital audio output interfaces are available, I2S and SPDIF. The I2S interface supports 2-ch LPCM and the SPDIF interface supports 8-ch LPCM or compressed audio,both at maximum 192kHz sample rate.

      All the functions pack into a small 4mm*4mmQFN32 package which saves the precious space in mobile devices.
