Doc ID 024009 Rev 1

Overview

The STV0910 features a high-speed DVBS2 forward error corrector (FEC) which is

designed to handle up to 270 channel-Mbits/s at its input. To feed the FEC the STV0910

implements two identical demodulators, each capable of handling QPSK legacy and DVBS2

modulation for satellite broadcast services.

The STV0910 integrates all the features needed to provide a low cost dual broadcast

satellite receiver solution including: integrated crystal oscillator, dual DiSEqC controller, dual

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.

Benefits

Multi-standard dual demodulation and decoding.

Allows an advanced, high-end set-top box or

receiver to be compatible with multiple markets

and legacy installations and so assists migration

to the advanced services.

SuperFEC™

For enhanced legacy QPSK performance.

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.

I

ntegrated DiSEqC 2.x 22-kHz and FSK

interfaces.

Reduces BoM cost whilst maintaining flexibility in

antenna control.

JTAG interface for boundary scan.

Allows simple and thorough board testing in

production.
