Digital camera USB interface IC

Product specification

SAA8117HL

1 FEATURES

• Medium resolution CCD sensors (PAL non-interlaced

mode) or VGA CCD sensors (progressive mode)

• D1 digital video input (8 bits YUV 4 : 2 : 2,

time multiplexed)

• Internal Pulse Pattern Generator (PPG) dedicated for

medium resolution Sharp or compatible sensors and

VGA sensors and for frame rate selection

• Video formatter (programmable CIF formatter and

compression engine) controlled via SNERT (UART)

interface

• Selectable output frame rate (1 fps in VGA, up to 15 fps

in CIF format)

• Video packetizer FIFO

• I2C-bus interface for communication between the USB

protocol hardware and the external microcontroller

• Integrated analog bus driver (ATX)

• Microphone/audio input to USB (FGA, ADC, PLL and

decimator filter)

• Integrated analog bus driver (ATX)

• Integrated main oscillator

• Miscellaneous functions e.g. power management,

PLL backup oscillator.

2 APPLICATIONS

• Low-cost desktop video applications with USB interface.

3 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).
