Introduction STV0367
1 Introduction
Intended mainly for use in iDTV sets and set-top boxes for the expanding European and
Asian markets, the STV0367 combines in one single digital receiver chip, all the legacy of
the popular and market-proven STV0362 and STV0297E devices.
The design of the STV0367 is optimized, in terms of cost and performance, for the most
advanced CAN tuners and silicon tuners available on the market and is compliant with both
DVB-T and DVB-C standards.
The STV0367 provides all demodulation and FEC functions required for the recovery of
DVB-C bitstreams with outstanding BER results. In addition, it includes several features that
give simple and immediate access to various quality and status monitoring parameters. It is
intended for the digital transmission of compressed television, video, sound, and data
services over cable and is fully compliant with ITU-T J.83 Annexes A/C or DVB-C
specification bitstreams.
For terrestrial DVB-T networks the STV0367 embeds robust algorithms to cope with multiple
interference sources as well as impulse noise effects. The channel equalizer is capable of
static and dynamic echo cancellation even in severe urban environments. The embedded
algorithms are enhanced to cope with out-of-guard interval echoes. Furthermore, specific
channel quality monitoring is available for acquisition and survey.
The RF signal level is monitored by a dedicated single-ended 8-bit ADC. The RF power can
be left under the control of the tuner, or it can be derived from the baseband power using a
dedicated power-split algorithm. If required, the tuner serial I²C bus can be isolated using
the STV0367 I²C bus repeater.
The STV0367 handles a wide range of symbol rates, ranging from the highest practical
rates to rates as low as 0.87 Mbaud, even when there is a significant frequency offset.
