Bi-CMOS INTEGRATED CIRCUIT
μ
PC2539
The
μ
PC2539 is data demodulator IC for FM receiver applying to Radio Data System in European countries and
Radio Broadcasting Data System in USA.
This IC carries out to extract 57kHz RDS signal from FM multiplex signal, demodulate data-stream, recover
bit-rate-clock, and discriminate SK signal in ARI system.
FEATURES
Adjustment-free
Built-in 57kHz band-pass-filter consist of switched capactiors.
High sensitivity.
Employing digital PLL.
Small outline plastic package
