DESCRIPTION

VXIS VX1937 TV encoder is a

stand-alone integrated circuit

that converts to 525-line (M)

NTSC or 625-line (B, D, G, H, I,

M, N, Nc) PAL composite video

and S-video outputs.

VX1937 integrates a digital

NTSC / PAL encoder with 8-bits

ADC and 10-bits DAC

interfaces.

A high level of integration and

performance makes the chip

ideal for a variety of stand-alone

and system-level integration

solutions.

FEATURES

Four 10-bits DAC for CVBS2

/ G / Y, Y / R / V, C / B / U

and CVBS1. Transfer rate
