Part Code
HDMI_Port _Processor The SiI9287 HDMI port processor is the second generation of HDMI devices that
support revision 1.3 of the HDMI specification. The main feature is as follows.
1) 4-input, 1-output HDMI port processor.
2) Integrated TMDS receiver and transmitter cores capable of receiving and trans-
mitting at 2.25Gbps.
3) Supports video resolutions up to 1080p, 60Hz, 12bit or 720p/1080i, 120Hz,12bit.
4) Receiver fully comply with DVI1.0, HDCP1.1 and HDMI1.3 specifications.
COFDM The STV0297E's demodulator is a complete QAM (quadrature amplitude modula-
tion) demodulation and FEC (forward error correction) solution that performs IF to
transport
stream block processing of QAM signals. It is intended for the digital transmission
of compressed television, sound, and data services over cable.
