Description
Output for signal quality indication (High = good)
RDS data output
Reference voltage
RDS input signal
Oscillator selector pin:
- open, closed to V_S = quartz oscillator
- closed to GND=external driven
Ground
Output for ARI indication:
- high when RDS+ARI are present
- high when only ARI is present
- low when only RDS is present
- undefined when nos signal is present
Filter output
Frequency selector pin:
Test mode pin:
Reset pin:
-100K to V_S = 17.328MHz
- open = 4.332MHz
- closed to V_S = 8.664MHz
- open = normal operation
- closed to V_S = testmode
- open=run mode
- closed to V_S = reset condition
