Terminal connection details
CTL 1 - 6
Programmable dividing ratio.
(Pull-down resistor incorp..)
OUT
Output frequency preset by
CTL 1~ 6.(Refer to the setting
procedure of output freq.)
FOUT
Constant output of the oscillator
source frequency.
(Built-in quartz crystal).
RESET
Stops output at RESET = L.
(Pull-up resistor incorporated.)
TEST
Used for testing the input
terminal. When CTL 4 is H,
output will be 1000 times
larger than the preset value at
TEST = H.
(Pull-down resistor incorp.)
EXC (8640N only) Serves as input terminal when
using an external clock by
changing to the built-in osc.
Effective when CSEL is H.
CSEL (8640N only) When this terminal is made H,
the external clock is selected.
(Pull-down resistor incorp.)
Unused terminals

CTL 1 ~ 6
When unused connect to Vdd.
When unused connect to GND.
When unused connect to GND.
When unused connect to GND.
