Overview

The LC7074 and the LC7074M are ICs for the RDS (radio data system) implemented by the EBU (European Broadcasting Union) and the RDBS (radio broadcast data system) implemented by the NRSC (National Radio System Committee) in the USA.

Features

• System that decode, synchronize and detect and correct

errors can easily be constructed by combining the

LC7074/M with an LA2230 series product.

• Reduces overhead in the microprocessor that decodes and

processes the RDS or MMBS/RDS data.

Functions

• Group synchronization.

RDS group synchronization.

MMBS/RDS group synchronization.

• Error detection and correction.

• Error detection function enable/disable selection.

• Serial data output.

• Serial data clock polarity selection.

• Data block start signal output.
