I have started to use an ADA2200 for the purpose of employing it as a Lock-in Amplifier.
For starting the operation, I am following the document - ADA2200SDP-EVALZ (Rev. 0) (analog.com).
On page 3, point no. 8, it is mentioned that "Verify that a square wave (~7.8125 kHz) is present at RCLK_OUT (J3). Connect RCLK_OUT to VINP (J7) with an SMA cable".
I am doing that, but getting a frequency of around 63 kHz. I am not sure why this is happening. I would be grateful if you could kindly help me sort this out.
Thank you in advance
