PIN DESCRIPTION PIN FUNCTION CLKn, CLKn LVDS, LVPECL CLK Inputs* Qn0:4, Qn0:4 LVDS Outputs VTA 50  Termination Resistors VTB 50  Termination Resistors V Positive Supply CC V Ground EE EP for QFN32, The Exposed Pad (EP) on the QFN32 package bottom is only thermally connected to the die for improved heat transfer out of package. The exposed pad must be attached to a heat sinking conduit. The pad is electrically connected to V . EE *Under open or floating conditions with input pins converging to a common termination bias voltage the device is susceptible to auto oscillation.
