These inputs are normally wired to V
CC
, GND or left unconnected (actual threshold voltages vary as a percentage
of V
CC
). Internal termination resistors hold unconnected inputs at V
CC
/2. If these inputs are switched, the function
and timing of the outputs may glitch and the PLL may require an addtional t
LOCK
time before all data sheet limits
are achieved.
XRK4993 should be tested one output at a time, output shorted for less than one second, less than 10% duty
cycle. Room temperature only.
Applies to CLKIN and FB_IN inputs only.
