Functions and Explanation
1
V
CC1
2.2 to 5.5
Power supply pin of a input amplifier and dividers. This pin must be
equipped with bypass capacitor (eg 1000 pF) to minimize ground
impedance.
2
IN
1.7 to 4.95
Signal input pin. This pin should be coupled to signal source with capacitor
(eg 1000 pF) for DC cut.
3
IN
1.7 to 4.95
Signal input bypass pin. This pin must be equipped with bypass capacitor
(eg 1000 pF) to minimize ground impedance.
4
GND
0
Ground pin. Ground pattern on the board should be formed as wide as
possible to minimize ground impedance.
5
SW1
H/L
Divide ratio control pin. Divide ratio can be determined by following applied
level to these pins.
6
SW2
H/L
These pins must be each equipped with bypass capacitor to minimize their
impedance.
7
OUT
1.0 to 4.7
Divided frequency output pin. This pin is designed as emitter follower
output. This pin can output 0.1 V
P-P

load.
This pin should be coupled to load device with capacitor (eg 1000 pF) for
DC cut.
8
V
CC2
2.2 to 5.5
Power supply pin of output buffer amplifier. This pin must be equipped
with bypass capacitor (eg 1000 pF) to minimize ground impedance.
