EP
The Exposed Pad (EP) on the QFN16 package bottom is thermally connected to the die for im-
proved heat transfer out of package. The exposed pad must be attached to a heatsinking con-
duit. The pad is electrically connected to the die, and must be electrically and thermally connected
to GND on the PC board.
1. In the differential configuration when the input termination pins (VTCLK, VTCLK) 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. Q/Q outputs have internal 50 W source
termination resistors.
2. VCC and GND pins must be externally connected to a power supply for proper operation.
