■ 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
