STB6000

®

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
