EP
The Exposed Pad (EP) on the QFN16 package bottom is thermally connected to the die for
improved heat transfer out of package. The exposed pad must be attached to a heatsinking
conduit. The pad is not electrically connected to the die, but is recommended to be electrically
and thermally connected to VEE on the PC board.
1. In the differential configuration when the input termination pins (VTx, VTx) are connected to a common termination voltage or left open, and
if no signal is applied on CLK/CLK input, then the device will be susceptible to selfoscillation.
2. All VCC and GND pins must be externally connected to a power supply for proper operation.
