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
