The TDA7333N circuit is a RDS/RDBS signal processor, intended for recovering the inaudible RDS/RBDS informations which are transmitted on most FM radio broadcasting stations.
The TDA7333N is an integrated circuit designed to recover Radio Data System (RDS) and USA Radio Broadcast Data System (RBDS) information transmitted on most FM radio stations. It features a 3rd-order high-resolution sigma-delta converter for multiplex sampling, mu-law digital decimation and filtering stages, and automatic group and block synchronization with a flywheel mechanism.
It demodulates European Radio Data System (RDS) and USA radio broadcast data system (RBDS).
The RAM buffer has a storage capacity of 24 RDS blocks and related status information.
