Output Clock A for Channel 1
May be a single-ended output or half of a differential
output with CLK1B being the other differential half.
I
Output Clock Supply Voltage
Supply voltage for CLK0A,B. If CLK2 is not used, this pin
must be tied to pin 7 and/or pin 24.
Output Clock B for Channel 0
May be a single-ended output or half of a differential
output with CLK0A being the other differential half.
If unused, this pin must be tied to VDD pin 24.
Output Clock A for Channel 0
May be a single-ended output or half of a differential
output with CLK0B being the other differential half.
Ground.
Must be connected to system ground. Minimize the
ground path impedance for optimal performance of this
device.
Core Supply Voltage.
The device operates from a 1.8, 2.5, or 3.3 V supply. A
0.1 µF bypass capacitor should be located very close to
this pin.
Ground Pad.
This is the large pad in the center of the package. Nine
or more vias should be used to connect this pad to a
ground plane. Device specifications cannot be
guaranteed unless the ground pad is properly connected
to a ground plane on the PCB.
