VTCLK
Internal 50 W Termination Pin for CLK
5,8,13,16
VCC
Positive Supply Voltage. All VCC pins must be externally connected to a Power Supply
to guarantee proper operation.

Q1
CML Output
Noninverted CLK output 1 with internal 50 W source termination resistor. (Note

VEE
Negative Supply Voltage. All VEE pins must be externally connected to a Power Supply
to guarantee proper operation.

Q0
CML Output
Inverted CLK output 0 with internal 50 W source termination resistor. (Note
2)15
Q0
CML Output
Noninverted CLK output 0 with internal 50 W source termination resistor. (Note
2)EP
Exposed Pad. The thermally exposed pad on package bottom (see case drawing) must
be attached to a heatsinking conduit. 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 resistor to VCC for proper operation.
