The data clock output is provided as a reference to clock the data into the device. As with the analog
output and the reference input it is recommended that the data clock is isolated from the application
circuit to remove common mode noise in the digital ground plane.
The output pins CKOUT and CKOUTB are designed to drive a bridged load to reduce the effect of
package inductance, and each pin has a nominal output resistance of 25 .
A transformer can again be used, the recommended device being a Mini-Circuits ADT4-1WT. The
ends of the secondary should be connected to CKOUT and CKOUTB through series 75 resistors,
and 100
should be connected to the wiper of a 100 variable resistor to provide an adjustable bias point for
the output signal. The variable resistor should be placed across the supply and ground rails of the
application circuit, and a 100nF capacitor placed from the wiper to application ground. (If the biasing
is not required connect the primary dot to ground). The data clock is then present at the other end of
the primary. A 50 PCB track should be used here. See figure 17.
