STV6111
8PSK/QPSK low-power 3.3-V satellite tuner IC
Data brief
Features
■ RF-to-baseband direct conversion architecture
■ Single 3.3-V DC supply, low consumption
■ Outstanding performance in heavily loaded
spectrum conditions
■ Input frequency range: 950 to 2150 MHz
■ Supports 1 to 60 Msymb/s using internal filter
■ RF-AGC or channel-AGC support
■ Extremely low-phase noise, compliant with
DVB-S2 requirements using fractional-N
synthesizer
■ Low external component count
■ Flexible crystal frequency output to drive the
demodulator and/or other tuner ICs
■ Continuously variable gain
■ Programmable 6 to 50 MHz cut-off frequency
(Butterworth 5th-order baseband filters)
■ Specific operating mode for symbol rates up to
220 Msymb/s
■ Compatible with 5-V and 3.3-V I2C bus
Applications
■ Direct broadcasting satellite (DBS), satellite
modems: BPSK, QPSK, 8PSK, 16/32 APSK
modulations
■ Set-top boxes, PCTV and iDTV
■ Outdoor units
Package
■ VFQFPN-32 5 x 5 x 1 mm3 with exposed pad
■ ECOPACK®, RoHS (2002/95/EC) compliant
