Clock input.
Use this pin when the
clock is input at PECL
level.
At this time, leave
Pin 19 open.
CLKP/E and CLKN/E
are complementary and

input.
Reset signal input.
When multiple
CXA3197R are
operated at the same
time in MUX.1A or
MUX.1B mode, the start
timing of the internal 1/2
frequency divider
circuits should be
matched.
At this time, the reset
signal is used; when the
reset signal is at TTL
level, Pin 22 is used and
Pins 23 and 24 are left
open. When the reset
signal is at PECL level,
Pins 23 and 24 are used
and Pin 22 is left open.
The reset signal polarity
can be set by Pin 39
(R POLARITY).
Leave the reset pin
open when other modes
are used.
RESETP/E and
RESETN/E are
complementary and
should be used together.
