Product specification

Low-voltage high performance mixer FM IF system

SA617

AC ELECTRICAL CHARACTERISTICS

T = 25°C; V = +3V, unless otherwise stated. RF frequency = 45MHz + 14.5dBV RF input step-up; IF frequency = 455kHz; R17 = 2.4k; R18

= 3.3k; RF level = –45dBm; FM modulation = 1kHz with ±8kHz peak deviation. Audio output with de-emphasis filter and C-message weighted

filter. Test circuit NO TAG. The parameters listed below are tested using automatic test equipment to assure consistent electrical

characterristics. 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.

NOTE:

1. The generator source impedance is 50Ω, but the SA617 input impedance at Pin 18 is 1500Ω. As a result, IF level refers to the actual signal

that enters the SA617 input (Pin 18) which is about 21dB less than the “available power” at the generator.
