deviation. Audio output with de-emphasis filter and C-message weighted filter. Test circuit
below are tested using automatic test equipment to assure consistent electrical characteristics. The limits do not represent
the ultimate performance limits of the device. Use of an optimized RF layout will improve many of the listed parameters.

The generator source impedance is 50 Ω, but the SA676 input impedance at IF_AMP_IN (pin 18) is 1500 Ω. As a result, IF level refers
to the actual signal that enters the SA676 input (IF_AMP_IN, pin 18), which is about 21 dB less than the ‘available power’ at the
generator.
