AD9915 is DDS manufactured by Analogue devices. I am unable to find the maximum power level of reference clock that can be applied to its evaluation board (also manufactured by analogue devices) from the datasheet. The IC assumes a differential Reference Clock, and evaluation board provides an interface for Single-ended reference clock and then converts it into differential using an IC named as ADCLK925BCPZ-WP. Can i apply a single-ended clock of +10dBm to this evaluation board without damaging AD9915
 

Re: AD9915 Reference Clock Maximum Power??

Up to the ADCLK925 datasheet,
Code: 
The inputs have center tapped, 100 Ω, on-chip termination resistors.
... i.e. 50Ω input impedance. For environment conditions between -40°C to 85°C they can do with min. 0.2 and max. 3.4Vp-p input voltage. i.e. between -1dBm and +23.6dBm.

The ADCLK925 will then provide the correct clk input levels to the AD9915.
