GENERAL DESCRIPTION
The SAA8117HL is a monolithic integrated circuit which
can be used in PC video cameras to convert D1 video
signals and analog audio signals to properly formatted
USB packets.
It is designed as a back-end for the SAA8110G or
SAA8112HL (general camera digital processing ICs) and
is optimized for use with the TDA8784/87 (camera
pre-processing IC) and the 83C51RC (microcontroller).
