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 STB089 9 supp or ts sea mle ss mi grat i on to D VB-S 2 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.
