CH7001C VGA to NTSC/PAL Encoder

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 composite 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 c.

Features

• Enhanced bandwidth and signal-to-noise ratio for higher video performance
• Integrated triple video rate 8-bit analog to digital converters for input RGB
• 3-line digital vertical filtering with pinprogrammable characteristics for optimum antiflicker and resolution
• On-chip phase-locked loop generates sampling clock from VGA horizontal sync
• Enhanced power management for selective circuit power-down
• Simultaneous composite/S-video output
• Horizontal and vertical position control
• Pin-programmable underscan/overscan mode
• On-chip reference generation and loop filter
• CMOS technology in.
