DescriptionSTi52112/4 1 DescriptionThe STi5211 is a standard definition, full back-end processor for satellite set-top boxes, compliant with ATSC, SMPTE VC-1, DVB-S2, DIRECTV, DCII and ARIB BS4 specifications. It provides very high performance for low-cost SD systems. With its enhanced performance compared to the STi5202, the STi5211 includes both VC-1 and H.264 video decoders for new, low bitrate applications.The main platform target for the STi5211 is the DVB-S2 zapper. Alternatively, the device can be used in a client box through IP over Ethernet, Multimedia over Coax Alliance (MoCA) or WiFi.Figure 1.STi5211 applicationsVCR PSTN Si3062 NOR/NAND IR RxAnalog CVBS/YCHDMI TMDS 1.48GHzSTb6110 ST8024 flashUSB 2.0MIIEthernet PHYEthernetPlugUSB 2.0 host plug STb6110FE0 - DVB-S2FE1 - DVB-S1DiSEqC0DiSEqC1 Discrete andpower circuitryDiscrete andpower circuitryPIOsKey scanning(no front panel micro-ctrl)MoCA PHYCoaxplugWiFiEMI/PCI 16 Buffer filterCEC / DDCYPbPrS/PDIFplug LR27/30MHz27/30MHz27/30M Features Microsoft VC-1, MPEG-2 and H.264 supportST40-300 CPU running at 450 MHz, high performance for Linux, Windows CE and OS21 based systemsDVB-S2 and DVB-S front-end integrated demodulators with a fully featured SD advanced decoder system-on-chip (SoC)Flexible ST231 based advanced video decoderST231 audio decoder at 450 MHz supporting WMA9, AC3, DD+, AAC, AAC+ with SPDIF outputSD display: 2 video, 3 graphics planes and background color with high quality filteringHDMI/HDCP output with standard definition (SD) component and composite outputUnified DDR2 16-bit interface operating at up to 333MHz Programmable transport interface (PTI) and transport stream (TS) merger with up to 2 digital external TS inputs, 2 internal inputs from internal demodulators and one TS from memory for network client USB 2.0 to support network interface and feature enhancement Nor-Flash, PCI, peripherals support10/100 Mbit/s Ethernet MAC with media independent interface (MII) and reduced MII (RMII)Advanced sec specifications.
