PLL-SPLIT VIF/SIF IC

In spite of the 1-pin filter configuration, 2-pin filter

characteristics are available by utilizing the dynamic AGC circuit.

Pin 14 (RF AGC OUTPUT)

A current mode output is available in the reverse AGC operation.

The maximum

Note: Connecting a nonpolarity capacitor of 1µF between pin14 and pin 18 improves AGC operating speed.

In that case, the capacitors between pin14/pin18 and ground should be removed.
