GENERAL DESCRIPTION
The SAA8115HL is the second generation of integrated
circuit applicable in PC video cameras to convert D1 video
signals and analog audio signals to properly formatted
USB packets.
This powerful successor of the SAA8117HL can handle up
to 15 fps in VGA format or 30 fps in CIF format. High
snapshot quality is achievable using the SDRAM interface
to an external memory.
It is designed as a back-end of the SAA8112HL (general
camera digital processing IC) and is optimized for use with
the TDA8784 to TDA8787 (camera pre-processing ICs).
