Digital PC-camera signal processor including

microcontroller and USB interface

SAA8116

FEATURES

• Embedded microcontroller (80C51 core based) for

control loops Auto Optical Black (AOB), Auto White

Balance (AWB), Auto Exposure (AE) and USB interface

control

• Compliant for VGA CCD and VGA CMOS sensors

(RGB Bayer)

• USB 1.1 compliant bus-powered USB device with

integrated power management and POR circuit

• RGB processing

• Optical black processing

• Defect pixel concealment

• Programmable colour matrix

• RGB to YUV transform

• Programmable gamma correction (including knee)

• Programmable edge enhancement

• Video formatter with SIF/QSIF downscaler

• Compression engine

• Flexible Measurement Engine (ME) with up to eight

measurements per frame

• Internal Pulse Pattern Generator (PPG) for wide range

of VGA CCDs (Sony, Sharp and Panasonic) and frame

rate selection

• Programmable H and V timing for the support of CMOS

sensors

• Programmable output pulse for switched mode power

supply of the sensor

• 3-wire interface to control an external pre-processor IC,

such as the TDA8787A: Correlated Double

Sampling (CDS), Automatic Gain Control (AGC) and

10-bit ADC

• Analog microphone/audio input to USB: Low DropOut

(LDO) supply filter, microphone supply, low noise

amplifier, programmable amplifier, PLL and ADC

• Integrated analog USB driver (ATX)

• Integrated main oscillator, including a clock PLL, which

derives 48 MHz main system clock from a 12 or 48 MHz

fundamental crystal.

APPLICATION

• USB PC-camera (video and audio).

GENERAL DESCRIPTION

The SAA8116 is a highly integrated third generation

USB PC-camera ICs. It is the successor to the

SAA8112HL and SAA8115HL. It processes the digitized

sensor data and converts it to a high quality, compressed

YUV signal. Together with the audio signal, this video

signal is then properly formatted in USB packets.

In addition, an 80C51 microcontroller derivative with five

I/O ports, I2C-bus, 512 bytes of RAM and 32 kbytes of

program memory is embedded in the SAA8116. The

microcontroller is used in combination with the

programmable statistical measurement capabilities to

provide advanced AE, AWB and AOB. The microcontroller

is also used to control the USB interface.
