STV0913BSB

Multi-standard advanced demodulator for satellite digital TV broadcast set-top boxes

STMicroelectronics 

Overview

Overview

STV0913

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 Private repeater isolates the (sensitive) RF tuner

for 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.

Integrated DiSEqC 2.x 22-kHz and FSK

interfaces.

To meet emerging energy standards for STBs.

Reduces BoM cost whilst maintaining flexibility in

antenna control.

JTAG interface for boundary scan.

Allows simple and thorough board testing in

production.
