Product Summary

The CH7001 is a VGA to NTSC/PAL encoder. It is stand-alone integrated circuit that converts analog VGA inputs directly into 525-line (M) NTSC or 625-line (B, D, G, H, I) PAL composite video and S-video outputs. A high level of integration and performance makes the CH7001C ideal for a variety of stand-alone and systemlevel integration solutions, including notebook computers and PC add-on graphics cards.


Parametrics

CH7001 absolute maximum ratings: (1)VDD relative to GND: - 0.5 to 7.0 V; (2)Input voltage of all digital pins 1: GND - 0.5 to VDD + 0.5 V; (3)TSC Analog output short circuit duration: Indefinite Sec; (4)TAMB Ambient operating temperature: - 55 to 125 °C; (5)TSTOR Storage temperature: - 65 to 150 °C; (6)TJ Junction temperature: 150 °C; (7)TVPS Vapor phase soldering (one minute): 220 °C.

Features

CH7001 features: (1)Enhanced bandwidth and signal-to-noise ratio for higher video performance; (2)Integrated triple video rate 8-bit analog to digital converters for input RGB; (3)3-line digital vertical filtering with pinprogrammable characteristics for optimum antiflicker and resolution; (4)On-chip phase-locked loop generates sampling clock from VGA horizontal sync; (5)Enhanced power management for selective circuit power-down; (6)Simultaneous composite/S-video output; (7)Horizontal and vertical position control; (8)Pin-programmable underscan/overscan mode; (9)On-chip reference generation and loop filter; (10)CMOS technology in 44-pin PLCC; (11)5V supply.
