CH7001C Description
Chrontel’s CH7001C VGA to NTSC/PAL encoder is a stand-alone integrated circuit that converts analog VGA inputs directly into 525-line (M) NTSC or 625-line (B, D, G, H, I) PAL posite video and S-video outputs. This circuit integrates a digital NTSC/PAL encoder with 8-bit ADC and DAC interfaces, a 3-line vertical filter and low-jitter phase-locked loop to create outstanding quality video with 24-bits-per-pixel...
