Input SYNC signal at TTL level.
The input polarity is switched by the
control register.
Leave this pin open when not used.
Input SYNC signal at TTL level.
The input polarity is switched by the
control register.
Leave this pin open when not used.
Input signal for phase comparison
HOLD.
Phase comparison is stopped, and
VCO oscillation frequency is held.
When not be hold, fix the pin as
follows.
When HOLDPOL register is "1", fix
this pin to low level.
When HOLDPOL register is "0", leave
this pin open or fix to high level.
Input the signal used to invert the
A/D converter sampling CLK.
Normally fix it to low level.
Programmable counter reset.
Normally fix it to high level or leave
open.
In programmable counter test mode,
set it to low level to call up the register
contents.
When not used, leave this pin open
or fix to high level.
CLK input for ADC operation check.
Input PECL level signal
complementally.
When using this pin, set CLK to
external input by the control register.
Leave this pin open when not used.
Low: EVEN mode
High: ODD mode
