| Digital Broadcast Reception LSI MN88413 Channel Decoder LSI for Digital Satellite Broadcast Reception I 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. I 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 I Applications * Digital satellite broadcast receivers Note: DSS and DIRECTV are registered trademarks of DIRECTV, Inc.
