Description
1
QUAL Output for signal quality indication (High = good)
2
RDDA RDS data output
3
VREF Reference voltage
4
MPX RDS input signal
Oscillator selector pin:
5
OSEL – open, closed to V_S = quartz oscillator
– closed to GND = external driven
6
GND Ground
Output for ARI indication:
– high when RDS+ARI are present
7
ARI – high when only ARI is present
– low when only RDS is present
– undefined when nos signal is present
8
FILOUT Filter output
Frequency selector pin:
9
FSEL ^{– 100 kHz to VS = 17.328 MHz}
– open = 4.332MHz
– closed to VS = 8.664 MHz
Test mode pin:
10
TM – open = normal operation
– closed to VS = test mode
Reset pin:
11 EXTRES – open = run mode
– -closed to VS = reset condition
12
V_S
Supply voltage
13
OSCIN Oscillator input
14 OSCOUT Oscillator output
