Capacitance
Notes:
4. These inputs are normally wired to V
5. PI6C3991 should be tested one output at a time, output shorted for less than one second, less than 10% duty cycle.
6. Applies to REF and FB inputs only. Tested initially and after any design or process changes that may affect these parameters.
Electrical Characteristics
P
a
termination resistors hold unconnected inputs at V
and the PLL may require an additional t
Room temperature only.
