MN88413

Digital Broadcast Reception LSI MN88413 Channel Decoder LSI for Digital Satellite Broadcast Reception s 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. s 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 s Applications Digital satellite broadcast receivers Note: DSS® and DIRECTV® are registered trademarks of DIRECTV, Inc. 1 2 AGC QIN IIN MN88413 s Block Diagram PLL0-2 CPO Offset canceler VSSA0-2 VDDA1-2...
