RDS Demodulator IC

PT2579

DESCRIPTION

PT2579 is a Radio Data System Demodulator IC utilizing CMOS Technology specially designed for

radio data system applications. The RDS data signal (RDDA) and the RDS clock signal (RDCL) are

provided as outputs for further processing by an ideal decoder / microcontroller. Anti-aliasing Filter (2nd

order), 57kHz band pass filter (8th order), reconstruction filter (2nd order), clocked comparator with

automatic offset compensation, biphase symbol decoder, differential decoder, and signal quality

detector are all built into a single chip having the highest performance and reliability. Pin assignments

and application circuit are optimized for easy PCB layout and cost saving advantages.
