Oscillator input
Testing output pin: 57kHz clock output
RDS clock output 1187.5Hz
RDS data output
Output for signal quality indication (High = good)
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
