■ Overview

The MN88413 is a channel decoder LSI that integrates functions for digital satellite communications and broadcast reception on a single chip.

The MN88413 supports both the Digital Video Broadcast (DVB) and the Digital Satellite System (DSS?) specifications.

It also supports a variable transport rate that can be set under program control using a fixed system clock frequency and can implement a channel decoder with a minimal number of external components.

■ Features

? Can be used in systems conforming to DVB, in US DIRECTV? systems, and in single carrier per channel (SCPC) communication systems.

? Integrates a 2-channel A/D converter, a variable rate QPSK demodulator, and forward error correction (FEC) on a single chip.

? Supports transfer rates from 1 Mbps to 90 Mbps.

? On-chip I/Q baseband signal offset voltage circuit and on-chip reference voltage circuit for the A/D and D/A converters.

? On-chip PLL circuit

? BER monitor function

? I2C bus master circuit for tuner control

? Supports LNB control clock and DiSEqC 1.0/1.1 and can output DiSEqC messages.

? General-purpose input and output ports

? On-chip boundary scan test circuit conforming to IEEE 1149.1

■ Applications

? Digital satellite broadcast receivers
