| (R) STB6000 QPSK DVB/DIRECTVTM direct conversion tuner IC DATA BRIEF 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 Application: Integrated silicon tuner VCO_BYP SYN_BYP VCCSCV 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.
