Output Clock 2.
CMOS output clock. If unused, this pin must be left floating.
Multi-Function Input.
This pin functions as a multi-function input pin. The pin function (OEB_all, OEB_01,
OEB_23, OEB_45, OEB_67, Frequency Select, or Reset) is user-selectable at time of
configuration using the ClockBuilder configuration utility
Power supply for clock outputs 0 and 1. May be operated from a 1.8, 2.5, or 3.3 V sup-
ply. A 0.1 μF bypass capacitor should be located very close to this pin. If CLK0/1 are not
used, this pin must be tied to pin 7 and/or pin 24.
Output Clock 1.
CMOS output clock. If unused, this pin must be left floating.
Output Clock 0.
CMOS output clock. If unused, this pin must be left floating.
Must be connected to system ground. Minimize the ground path impedance for optimal
performance of the device.
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.
This is the large pad in the center of the package. See"6. Recommended PCB Layout"
on page 19 for the PCB pad sizes and ground via requirements. Device specifications
cannot be guaranteed unless the ground pad is properly connected to a ground plane
on the PCB.
