GENERAL DESCRIPTION
The SAA8113HL is a 2nd generation camera Digital
Signal Processor (DSP) designed for low-cost DTV
applications. It integrates the DSP core, the Pulse Pattern
Generator (PPG), the 80C51 microcontroller and the
VDAC in one IC. It is the successor of the SAA8110G,
dedicated to analog output cameras.
The SAA8113HL must be applied together with an analog
front-end that includes a Correlated Double Sampling
(CDS), an Automatic Gain Control (AGC) and an
Analog-to-Digital Converter (ADC). This may be the
TDA8786 or the TDA8784.
The PPG generates the timing pulses to drive medium
resolution PAL/NTSC complementary mosaic CCD
sensors (512
× 492 NTSC and 512 × 582 PAL).
The input of the DSP is 10 bits with a maximum pixel
frequency equal to 9.66 MHz. The DSP core processes
this sensor signal to a standard video output signal. The
SAA8113HL output is an analog CVBS video signal.
The microcontroller provides the settings for the IC
registers from EEPROM at power-up or reset and controls
the AWB, AE and AOB loops. It also provides a hardware
I2C-bus interface, so the microcontroller can be used as an
I2C-bus slave. The software code is embedded in an
internal ROM but it is also possible to use a combined data
and address bus, connected to an external program
EPROM.
A built-in power management function allows the power
dissipation to be optimized.
