Overview
STV0913
Overview
The STV0913 is intended for use with zero IF balanced IQ tuners (I, IB, Q, QB) with RFAGC
level control and I2C register control. The demodulator is capable of processing DVB-S2,
DVB-S and DTV legacy signals.
The STV0913 integrates all the features needed to provide a low-cost broadcast satellite
receiver solution including: integrated crystal oscillator, DiSEqC controller, tuner I2C
repeater, FSK modem, ancillary DACs and ADCs and many unattributed general purpose
input/output ports for peripheral control.
Advanced power saving features have been implemented, the LDPC stops once the
solution is sufficiently converged and the various blocks of the IC (demodulator, LDPC,
Legacy FEC, and so on) may be completely shut down if not required.
Features
Benefits
Multi-standard demodulation and decoding.
Allows an advanced set-top box or receiver to be
compatible with multiple markets and legacy
installations and so assists migration to the
advanced services.
Multi-tap equalizer.
Improves reception in poor RF group-delay and
reflection conditions (narrow transponders,
SMATV installations, poor connectors,
unterminated branched cables).
DVB common interface compliant.
Allows interface to DVB-CI+ module for decoding
encrypted content.
I2C serial bus interface, including private repeater
for tuner.
Private repeater isolates the (sensitive) RF tuner
from potential digital noise from the host
processor.
Fine-grained power management.
Allows power to be reduced according to usage
and standby strategy.
Best-in-class, low-power standby mode.
To meet emerging energy standards for STBs.
Integrated DiSEqC 2.x 22-kHz and FSK
Reduces BoM cost whilst maintaining flexibility in
antenna control.
interfaces.
JTAG interface for boundary scan.

Allows simple and thorough board testing in
production.
