CH7002D - Scalable VGA to NTSC/PAL Encoder

Description

Chrontel’s CH7002 VGA to NTSC/PAL encoder is a standalone integrated circuit which provides a PC 99 compliant solution for TV output.

It accepts RGB analog inputs directly from VGA controllers and converts them directly into NTSC or PAL TV format, with simultaneous composite and S-Video outputs.

Features

  • Fully integrated solution for PC to TV display.
  • TrueScale TM rendering engine supports underscan operation for both 640x480 or 800x600 inputs †.
  • Advanced 3-line digital flicker filtering with programmable algorithm selections †.
  • Fully programmable through I2C port or hardware (pin-based) controls.
  • Wide range of VGA software drivers for full synchronization and image positioning.
  • Auto-detection of TV presence.
  • Programmable power mana.
