Description The HD49815TF is a CMOS IC that has been developed as a digital signal-processing IC for CCD-camera digital-signal-processing systems. Features • The HD49815TF provides camera-signal processing, TG, SSG, zoom, and D/A functions and other functions in a single chip and supports high system-integration level. • In conjunction with the HD49323AF-01 (CDS/AGC + 10-bit ADC) and the control microcomputer, the HD49815TF forms a three-chip kit that can implement an optimal CCD-camera digital-signal-processing system. • The HD49815TF provides the zoom function and controls the 1- to 256- times linear zoom. It also provides the half-mirror function. • Since the HD49815TF can be made compatible with the former product, HD49811TFA, through software, a shorter development term is enabled. • Since software controls AWB, AE, and AF, any protocol can be prepared according to the camera shooting conditions. • Programmable TG enables use of any CCD device. Functions • CCD-sensor drive-pulse generation (TG) • Digital AGC (automatic gain control) • Color signal separation circuit • RGB matrix • RGB gain • RGB and Y gamma • Color-difference matrix • Enhancer • RGB and Y setup • Digital I/F (4:2:2) • Zoom control • Mirror reversal • Synchronization signal generator for encoding (SSG) • AWB, AE, and AF detection • Two-channel 8-bit D/A converter
