Features

220 Msymb/s

■ RF-to-baseband direct conversion architecture

■ Single 3.3-V DC supply, low consumption

■ Compatible with 5-V and 3.3-V I C bus

Applications

■ Outstanding performance in heavily loaded

spectrum conditions

■ Direct broadcasting satellite (DBS), satellite

modems: BPSK, QPSK, 8PSK, 16/32 APSK

modulations

■ Input frequency range: 950 to 2150 MHz

■ Supports 1 to 60 Msymb/s using internal filter

■ RF-AGC or channel-AGC support

■ Set-top boxes, PCTV and iDTV

■ Outdoor units

■ Extremely low-phase noise, compliant with

DVB-S2 requirements using fractional-N

synthesizer

Package

■ VFQFPN-32 5 x 5 x 1 mm with exposed pad

■ Low external component count

■ ECOPACK , RoHS (2002/95/EC) compliant

■ Flexible crystal frequency output to drive the

demodulator and/or other tuner ICs

Description

■ Continuously variable gain

■ Programmable 6 to 50 MHz cut-off frequency

The STV6111 satellite tuner is a direct-conversion

(zero IF) receiver for digital TV broadcasting.
