SPCA717A
© Sunplus Technology Co., Ltd.
Proprietary & Confidential
231 NOV. 11, 2002
Preliminary Version: 0.1
DIGITAL VIDEO ENCODER FOR VIDEO CD
1.GENERAL DESCRIPTION
The SPCA717A is designed specifically for VideoCD, video games
and other digital video systems, which require the conversion of
digital YCrCb (MPEG) data to analog NTSC/PAL video. The
device supports a glue-less interface to most popular MPEG
decoders. The SPCA717A supports worldwide video standards,
including NTSC (N America, Japan) PAL-B, D, G, H, I (Europe,
Asia), PAL-M (Brazil), PAL-N (Uruguay, Paraguay), and PAL-Nc
(Argentina). Furthermore, the SPCA717A operates with a single
2x clock and can be powered with a single 3.3V supply. The
composite analog video signal is output simultaneously onto two
outputs. Therefore, it allows one output to provide base-band
composite video while the other drives a RF modulator. As a slave,
the SPCA717A automatically detects the input data formats
(PAL/NTSC, CCIR601) and switches internally to provide the
proper format on the outputs. This feature, along with the
on-board voltage reference and single clock interface, makes the
SPCA717A extremely simple to use. In addition, use of 2x
over-sampling on-chip simplifies external filter design resulting in
reduced overall system cost.
