| STB0899 Multistandard advance demodulator STB0899 Digital TV satellite set-top boxes DATA BRIEF DESCRIPTION The STB0899 advanced demodulator from STMicroelectronics enables digital set-top boxes to process base-band DVB-S2 signals into digital video transport stream data. This data is then ready to be fed directly to the STB decoder. By incorporating the DVB-S standard, the STB0899 supports seamless migration to DVB-S2 services. The STB0899 and STB6100 silicon tuner may be coupled with a decoder from ST's OMEGA range, thus forming a complete silicon solution for DVB-S / DVB-S2 set-top boxes. The interface between these devices has been designed to ensure simple layouts and the lowest possible bill of materials cost. Package (208 pin PQFP package) xxxx Figure 1.
