LIMITING VALUES

Limiting values under operational conditions

The tuner can be guaranteed to function properly under the following conditions.

Notes

1. Sinusoidal ripple voltage superimposed on the 5 V supply voltage in the frequency range of 20 Hz to 500 kHz.

Criteria for TV interference >57 dB.

2. For detailed information about the address decoding, refer to Chapter “Application information”.
