ADAU1781 Clock Output

Hi I'm trying to use the Master Clock output on the ADAU1781 eval board. I have all things set up as they are described in the startup guide, and my MCLK source switch is set to OSC. I was checking the MCKO pin with an oscilloscope and nothing was appearing, until I zoomed in on the y axis to a 20mv scale. Clock output appears but is under 20mv. Is it normal for the clock's amplitude to be so small?
