CML Output
Noninverted Differential Output 0 with Internal 50 W Source Termination Resistor. (Note 2)
EP
Exposed Pad. Thermal pad on the package bottom must be attached to a heatsinking
conduit to improve heat transfer. It is recommended to connect the EP to the lower
potential (VEE).
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 and CLK, then the device will be susceptible to selfoscillation.
2. CML outputs require 50 W receiver termination resistors to VCC for proper operation.
