By default, a shunt is placed on pins 2 and 3 to enable the outputs.
6 Output Clock
The LMK1C1104 fans out four LVCMOS outputs. The outputs can be loaded using the pullup and pulldown
footprints. No resistor has been soldered in those footprints.
The EVM board supports up to eight clock outputs for pin-compatible TSSOP packaged devices in the industry
standard footprint. The LMK1C1104 uses four of the 8 outputs shown in
Y2, and Y3.
