HD49815TF Datasheet | Hitachi Semiconductor

Description The HD49815TF is a CMOS IC that has been developed as a digital signal-processing IC for CCD-camera digital-signal-processing systems. 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 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 microputer, the HD49815TF forms a three-chip kit that can implement an optimal CCD-camera digital-signalprocessing system. - The HD49815TF provides the zoom function and controls the 1- to 256- times linear zoom. It also provides the half-mirror function. Features (cont) - Since the HD49815TF can be made patible 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.
