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.
