STB0899
Multistandard advance demodulator STB0899
Digital TV satellite set-top boxes
Rev. 1
DESCRIPTION
The STB0899 advanced demodulator from
STMicroelectronics enables digital set-top boxes
to process base-band DVB-S 2 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
STB0 89 9 su pp ort s s ea mle ss migr at ion to DV B-S2
services.
The STB 0899 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.
