STB6000
QPSK DVB/DIRECTV
TM
direct conversion tuner IC
Description
The STB6000 ASIC is a highly integrated, low
cost direct conversion (zero IF) tuner IC for
digital broadcast satellite (DBS) television
applications.
This device includes an LNA, down-converting
mixers, baseband low pass filters, gain control,
on chip VCO and a low noise PLL. Its wide gain
control range is well suited for low symbol rate
applications.
The STB6000 is controlled by a simple two wire
interface and has been designed to minimize the
external bill of materials to reduce manufacturing
costs and to simplify the board layout. The
reduced component count ensures greater
system reliability leading to increase consumer
satisfaction.
When used together, the STB6000and ST's
successful STV0299 BPSK/QPSK deomdulator IC
combine to form a highly cost effective complete
satellite front end that can seamlessly interface to
ST's OMEGA range of set-top box decoders.
Packaged in a small QFN 32-pin package, it is ideal
for low cost DBS design.
Application: Integrated silicon tuner
