1 / 14 page ![]() Description The CXA1645P/M is an encoder IC that converts analog RGB signals to a composite video signal. This IC has various pulse generators necessary for encoding. Composite video outputs and Y/C outputs for the S terminal are obtained just by inputting composite sync, subcarrier and analog RGB signals. It is best suited to image processing of personal computers and video games. Features • Single 5V power supply • Compatible with both NTSC and PAL systems • Built-in 75 Ω drivers (RGB output, composite video output, Y output, C output) • Both sine wave and pulse can be input as a subcarrier. • Built-in band pass filter for the C signal and delay line for the Y signal • Built-in R-Y and B-Y modulator circuits • Built-in PAL alternate circuit • Burst flag generator circuit • Half H killer circuit Applications Image processing of video games and personal computers Block Diagram and Pin Configuration Structure Bipolar silicon monolithic IC Absolute Maximum Ratings • Supply voltage VCC 14 V • Operating temperature Topr –20 to +75 °C • Storage temperature Tstg –65 to +150 °C • Allowable power PD CXA1645P 1250 mW dissipation CXA1645M 780 mW Recommended Operating Condition Supply voltage VCC1, 2 5.0 ± 0.25 V – 1 – CXA1645P/M E93411A41-ST RGB Encoder Sony reserves the right to change products and specifications without prior notice.
