描述 Description

IT9320 is a series of bridge ICs that convert digital video and audio input to the USB packet output.  The series includes IT9323TE, IT9325TE, and IT9327G. The packaging for IT9323TE and IT9325TE is thin quad flat pack (TQFP) with 144 pins and exposed E-pad, while that for IT9327G is thin-profile fine-pitch ball grid array (TFBGA) with 196 balls.  IT9323TE supports input video data rates up to 3840x2160 30Hz, while IT9325TE and IT9327G support input video data rates up to 3840x2160 60Hz. Output video data rates up to 3840x2160 30Hz are supported by IT9323TE, IT9325TE, and IT9327G. The main input of IT9320 is LVTTL digital video interface with external H- and V-Sync, and the output of IT9320 is USB 3.1 Gen 1 (SuperSpeed USB) interface. The digital video signal received from the LVTTL input is converted into USB Video Class (UVC) video streams and sent through the output interface.  No video compression other than chroma sub-sampling is performed in the process of data conversion, so the quality of the video can be well preserved. IT9320 is also equipped with several video processing engines, which can be enabled to pre-process the video to better meet the application's requirements.  In addition to video, IT9320 also has digital audio input and output interface.  The digital audio signal received from the digital audio input interface is output as USB Audio Class (UAC) audio stream.
