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 (V
SSd
) and the ground for the
transistor (V
SSa
) 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.
