AA9300
INTEGRATED CCD IMAGE SIGNAL PROCESSOR WITH EMBEDDED FLASH
DESCRIPTION
The AA9300 is a multi-chips package which integrates DSP, AFE(Analog Front End), VD(Vertical Driver) and
Reset (Voltage Detector with Delay) parts. The DSP is for CCD signal processing with a CCD timing generator
and video encoder with two 10 bit DACs. It supports general 510H/760H CCD CMYG color filter array and all
signal terminals those are to interface the CCD. The AA9300 adopted several algorithms to image quality
improvement and resolution and it can be adjusted by internal registers. It is provided with AE/AWB functions,
dynamic range enhancement and adaptive digital noise filter. A better image processing algorithm can be
adopted through firmware upgrade owing to built-in FLASH memory. Besides, external EEPROM for parameter
storage is needless. It provides a superior flexibility for gamma processing, H/V aperture and color space
conversion which are implemented using parameter and filter coefficients download method. Many external
interface protocols are also supported; those are SPI master/slave, UART, I2C master/slave, GPIOs, and so
forth.
The AFE is a complete analog signal processor for CCD application. The signal chain consists of a correlated
double sampler (CDS), a digitally controlled variable gain amplifier (VGA), and a black level clamp. It offers 10-bit
ADC resolution. It features a 25 MHz single-channel architecture designed to sample and conditions the outputs
of interlaced and progressive scan area CCD arrays.
The AA9300 also embeds a vertical clock driver with 3 levels of output voltage and a power reset generator to
detect a fixed voltage at the power up or down procedure to generate a reset signal. There is a typical 150mV
hysteresis range for different 3.3V system to prevent the system from crashing during power supply fluctuation.
