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
The scan rate converter transforms the VGA
horizontal scan-rate to either NTSC or PAL
scan-rates. The resulting YUV signals are set to
external frame buffer that is 16MB and supports up
to
1280x1024 SXGA
mode. (1600x1200 UXGA workable)
