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
up to 27 MHz.

BAR test patterns.
Only one Crystal (27 MHz)
required.
Adjustable sharpness,
brightness, contrast,
saturation and hue.
Simultaneous composite /
S-video output.
Selectable TV output format,
composite, S-video, YUV or
RGB for SCART.
Build in OSD.
CMOS technology in 128-pin
PQFP.
3.3V supply.
