Functions and Explanation

Must be connected bypass capacitor (e.g. 1 500 pF) to minimize

ground impedance.

Must be connected to the system ground with minimum inductance.

Ground pattern on the board should be formed as wide as possible.

(Track length should be kept as short as possible)

Must be coupled with capacitor (e.g. 1 500 pF) for DC cut.

Supply voltage 5.0 ± 0.5 V for operation. Must be connected bypass

capacitor (e.g. 1 500 pF) to minimize ground impedance.

Can be used for auto gain control. The control can be governed by

supply voltage to this pin. AGC performance can be adjustable by

RAGC value. (e.g. 15 Ω).

Input frequency from an external VCO output.

Must be coupled with capacitor (e.g. 1 500 pF).
