We are driving the reference input of the device with a AD8170.
The output of the AD8170 is a 66MHz square wave with a slew rate of 600V/uSec,
1.2Vp-p.
Is this signal applicable with the ADF4360-5 device?

 

The REFIN input is a CMOS logic input, so therefore, you can either AC couple a
min signal level of 0.7volts or DC couple a TTL/CMOS square wave input signal.
In your case, you could AC couple your input signal.
