Single chip STV0362

Product Description

STV0362 - Low-power and ultra compact DVB-T single chip receiver DVB-H broadcast compliant - STMicroelectronics

DESCRIPTION

The STV0362 inherits the functionality of the

STV0361 device and embeds new functionalities

required by the DVB-H standard at the physical

layer side. The STV0362 features the full DVB-T

and DVB-H standards framing structure, channel

coding and modulation. The symbol, timing and

carrier recovery loops are fully digital and sized in

order to match the state-of-the-art RF downconverter

devices.

The STV0362 is compatible with direct

conversion silicon tuners and is featuring two

high-performance differential 12-bit ADC for I and

Q channels. The tuner baseband power is

controlled by a classic AGC loop, and the RF

level is monitored by a dedicated single-ended 8-

bit ADC.

The terrestrial DVB-T network can be subject to

several interference sources which are the

neighboring digital and analog channels, as well

as the in-band analog channels. The STV0362

cancels these interference sources and removes

the effects of impulse noise. The channel

equalization is capable of static and dynamic

echo canceling even in severe urban

environments.

The embedded high-performance algorithms are

enhanced to cope with out-of-guard interval

echoes; specific channel quality monitoring is

available for acquisition and survey.

The specific power handling constraints are

primarily addressed by both technology and clock

rate management. The efficiency of channel

acquisition and re-acquisition also minimizes

power consumption.

The STV0362 relies on the decoder multimedia

processor to manage the MPE-FEC and to

control time slicing while operating in DVB-H

mode.
