STV0288

DVB-S and DIRECTVTM QPSK receiver with autoscan feature

DATA BRIEF

DESCRIPTION

STMicroelectronics introduces the STV0288, its
latest DVB and DIRECTV
which adds blind scan capability and DiSEqC 2.0 to
the industry-leading STV029 9 and provides a c ost
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 (FE C)
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 f rom 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 DIRECTV
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 6 0 Msps.
The chip outputs MPEG transport streams and
interfaces seamles sly to the p acket demultiplexers
embedded in the ST Omega chip family. Its low
power consumption, sm all package and low bill of
material makes it perfect for all satellite
applications.
