E-TDA7479AD

Overview

The E-TDA7479AD is a single-chip RDS demodulator and filter manufactured by STMicroelectronics. It recovers inaudible RDS information transmitted by FM radio broadcasting stations, operating in accordance with EBU specifications. The device features purely digital RDS demodulation without external components and includes an integrated 57 kHz bandpass filter. It supports ARI signal indication and provides RDS signal quality output. The component utilizes low noise CMOS technology for low radiation and operates with a standard 4.332 MHz crystal oscillator, with optional frequencies of 8.664 MHz and 17.328 MHz.
