Power supply pin of a input amplifier and dividers. This pin must be
equipped with bypass capacitor (eg 1000 pF) to minimize ground
impedance.
Signal input pin. This pin should be coupled to signal source with capacitor
(eg 1000 pF) for DC cut.
Signal input bypass pin. This pin must be equipped with bypass capacitor
(eg 1000 pF) to minimize ground impedance.
Ground pin. Ground pattern on the board should be formed as wide as
possible to minimize ground impedance.
Divide ratio control pin. Divide ratio can be determined by following applied
level to these pins.
These pins must be each equipped with bypass capacitor to minimize their
impedance.
Divided frequency output pin. This pin is designed as emitter follower
output. This pin can output 0.1 V
This pin should be coupled to load device with capacitor (eg 1000 pF) for
DC cut.
Power supply pin of output buffer amplifier. This pin must be equipped
with bypass capacitor (eg 1000 pF) to minimize ground impedance.
