Product Details

Description



Features:

· Integrated switched capacitor filter
· Demodulates European Radio Data System (RDS) or the USA Radio Broadcast Data System (RBDS) signals
· Oscillator frequencies: 4.332 or 8.664 MHz
· Integrated ARI clamping
· CMOS device
· Single supply voltage: 5 V
· Extended temperature range: -40 to +85 °C
· Low number of external components.


Application

The RDS/RBDS system offers a large range of applications from the many functions that can be implemented. For car radios the most important are:
· Program Service (PS) name
· Traffic Program (TP) identification
· Traffic Announcement (TA) signal
· Alternative Frequency (AF) list
· Program Identification (PI)
· Enhanced Other Networks (EON) information.

Notes
1. Human body model (equivalent to discharging a 100 pF capacitor through a 1.5 k series resistor).
2. Machine model (equivalent to discharging a 200 pF capacitor through a 0 series resistor and 0.75 H inductance).


Description

The RDS/RBDS demodulator is a CMOS SAA6581T with integrated filtering and demodulating of RDS/RBDS signals coming from a multiplexed input data stream. Data signal RDDA and clock signal RDCL SAA6581T are provided as outputs for further processing by a suitable microcomputer, for example CCR921 and CCR922.

The SAA6581T replaces SAA6579 in function and pin-compatibility.
