Explanation of Terminals
Terminal Function
Name
CTL1 to 6
Programs dividing ratio. (pull-down resistor incorporated)
OUT
Output frequency preset by CTL1~6.
(Refer to the setting procedure of output frequency)
FOUT
Constantly outputs the oscillation source frequency of
built-in quartz crystal.
RESET
Stops output at RESET="L". (Pull up resistor incorporated)
TEST
Used for the input terminal for testing. When CTL4 is H, output
will be 1000 times larger than the preset value at TEST-"H".
(Pull-down resistor incorporated)
EXC
Serves as input terminal when using an external clock by
(8640N only)
changing to the built-in oscillator. Effective only when CSEL is H.
CSEL
When this terminal is made H, the external clock is selected
(8640N only)
(Pull down resistor incorporated).
Note: treatment of empty terminals. When RESET terminal is not used, this
should be connected to VDD, when TEST terminal, CSEL terminal, and CTL1 to
6 terminals are not used, to GND.
