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 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.
