3 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.
