Clock Time Base Usage Notes
When using the clock time base output function, the output pin (BO1) pull-up resistor must have a value of over 100 k
.
The use of a Schmitt input in the microcontroller that accepts this signal is recommended to reduce chattering. This is to
prevent degradation of the VCO C/N characteristics when combining with a loop filter that uses the internal transistor
provided to form a low-pass filter. Although the ground for the clock time base output pin (VSSd) and the ground for the
transistor (VSSa) are isolated internally on the chip, applications must take care to avoid ground loops and minimize
current fluctuations in the time base pin to prevent degradation of the low-pass filter characteristics.
