Main ICs
IC207: COFDM DECODER (Coded Orthogonal Frequency Division Multiplexing)
Part Number : STV0362 SHARP Code: RH-IXB964WJZZQ
The STv0362 is a single-chip demodulator using COFDM and is intended for digital terrestrial receivers using compressed video, sound and data
services. It converts IF or base band differential signals to MPEG-2 transport stream format by processing OFDM carriers. The STv0362 is fully
compliant with the DVB-T specifi cation (ETS 300 744) and Nor Dig Unifi ed specifi cation.
IC1951: HDMI RECEIVER (High Defi nition Multimedia Interface)
Part number : Sii9025 SHARP Code : VHISII9025+-1Q
The Sii9025 is a compliant with the latest HDMI 1.2 (High Defi nition Multimedia Interface) specifi cation. Backward compatibility with DVI 1.0 allows
HDMI systems to connect to existing DVI 1.0 hosts. The SiI9025 is capable of receiving and outputting two channel digital audio at up to 192 kHz-
an excellent solution for Digital TVs. An S/PDIF port supports up to 192 kHz audio. The SiI9025 also comes pre-programmed with HDCP keys,
greatly simplifying the manufacturing process, while providing the highest level of HDCP key security.
This IC includes the main features show below:
1- Dual-Input HDMI 1.2, HDCP 1.1 and DVI 1.0 compliant receiver.
2- Integrated TMDSR core.
3- Digital video interface supports video processors:
• 24-bit RGB/YCbCr 4:4:4
• 16/20/24-bit YCbCr 4:2:2
• 8/10/12-bit YCbCr 4:2:2 (ITU BT.656)
• 12-bit DMO (Digital Multimedia Output) RGB/YCbCr 4:4:4 (clocked with rising & falling edges)
• Color Space Conversion for both RGB-to-YCbCr and YCbCr-to-RGB (both 601 and 709)
• Auto video mode configuration simplifies system firmware design
