STV0288

Rev. 1

DESCRIPTION

STMicroelectronics introduces the STV0288, its

which adds blind scan capability and DiSEqC 2.0 to

the industry-leading STV0299 and provides a cost

reduction path or new products.

The STV0288 contains two 8-bit analog-to-digital

converters for I-input and Q-input, a QPSK

demodulator, and a forward error correction (FEC)

unit having both an inner (Viterbi) and an outer

(Reed-Solomon) decoder. The device accepts

baseband differential signals as I and Q inputs.

High-performance clock generation is made from

an external reference which can vary from 4 to 30

MHz with respect to the analog to digital conversion

which is performed by two 8-bit ADC. The FEC unit

is compliant with

the

DSS

specifications. Processing is fully digital and an

on-chip performant state-machine enables blind

search of satellite transponders without a-priori

knowledge of symbol rate. Thanks to this new

feature, the amount of software required for the

driver to operate the demodulator chip is drastically

reduced versus the previous generation.

The

high

sampling

rate

facilitates

the

implementation

of

low-cost,

direct

conversion

tuners. The STV0288 is controlled via an I²C

interface.

The device operates up to 120 MHz and can

process variable modulation rates, up to 60 Msps.

The chip outputs MPEG transport streams and

interfaces seamlessly to the packet demultiplexers

embedded in the ST Omega chip family. Its low

power consumption, small package and low bill of

material

makes

it

perfect

for

all

satellite

applications.
