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
廬
) 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.
