Introduction
SB10 is a high quality NTSC/PAL video decoder module intended as a demonstration and evaluation
platform for the
SingMai PT4 video decoder IP core
.
The module accepts PAL or NTSC encoded CVBS (composite) inputs, either differential twisted pair
or single ended coaxial formats. The video is amplified, clamped and converted to digital video
using a 10-bit ADC clocked at 54MHz. An Altera FPGA is programmed with the PT4 video decoder,
which performs high quality line comb decoding of the video input. Both lock modes of the PT4
are supported – the voltage controlled oscillator (VCO) mode and the fast direct digital synthesis
(DDS) mode.
The BT656 output of the PT4 drives an HDMI transmitter allowing evaluation of the IP on a
monitor or waveform analyser. The HDMI output is set to 576i (PAL) or 480i (NTSC).
