The LMK61PD0A2 has several control pins dedicated for control of output format, output frequency, and
output enable control. These control pins can be configured through the jumpers shown in
Table 5
and
Table 6
.
Jumpers FS1, FS0, OS, and OE can be used to configure the corresponding control pin to either high or
low state by strapping the center pin to
VDD
position (tie pins 2-3) or
GND
position (tie pins 1-2),
respectively. Connections from the
VDD
position to the device supply or from the
GND
position to the
ground plane are connected by 1.5-k
Ω
resistors.
