LVPECL Output
Differential LVPECL Clock Outputs, (banks A and B) Typically terminated with 50 W
resistor to VCC – 2.0 V.
GND
Power Supply
Negative Supply Voltage
VCC
Power Supply
Positive supply voltage. All VCC pins must be connected to the positive power supply
for correct DC and AC operation.
EP
The exposed pad (EP) on the QFN32 package bottom is thermally connected to the
die for improved heat transfer out of the package. THe exposed pad must be attached
to a heatsinking conduit. The pad is electrically connected to GND.

QA[02], QA[02] are active. Deassertion of
OEA can be asynchronous to the reference
clock without generation of output runt pulses
QA[02] = L, QA[02] = H (outputs disabled). Assertion of
OE can be asynchronous to the reference clock without
generation of output runt pulses
