This pin can output either DSYNC
signal or DIVOUT signal.
It can be selected by the control
register.
In addition, the output polarity can be
selected by the control register.
UNLOCK signal output.
Make a discrimination between lock
and unlock in the analog manner by
connecting the external circuit.
Leave this pin open when not used.
Do not connect this pin to neither
power supply nor GND.
Digital power supply for PLL.
Digital GND for PLL.
TTL output power supply for PLL.
External pin for PLL loop filter.
External pin for PLL loop filter.
Connect an external resistor (3k )
to supply a stabilized current to the
inside of the IC. (charge pump
current, etc.)
Connect this pin to GND via 0.1µF
ceramic capacitor connected as
close to the pin as possible.
The band gap voltage is output.
