U2758M-B

DAB Channel Decoder

Description

The channel decoder chip set for the DAB receiver

consists of 4 ICs (U2758B-B, U2757M-B, a dynamic

RAM 256 × 4 bit and a digital signal processor, e.g.,

MT DSP56166). The U2758M-B performs the program

selection, de-interleaving and Viterbi decoding.

Electrostatic sensitive device.

Observe precautions for handling.

Features

U2758M-B supports all 4 transmission modes of

EUREKA 147 DAB preliminary system definition

and ETSI DAB standard (ETS 300 401)

–

Soft decision 384 kbit/s Viterbi decoder

PRBS descrambler

Reliability information calculation

CRC checksum comparison

Processing of FIC and up to 6 application channels

Parallel use of up to 8 U2758M with separate appli-

cation selection possible
