I bought ADA2200 to design lock-in amplifier. actually I boughtADA2200 EVAL-Z board. When I use internal resonator 400kHz the board working. But When I use external clock to clock in pin (properly arranged jumper configuration) 500kHz 3v sine wave signal, there is no respond. I checked RCLK pin there is no signal also synco pin did not respond to me. what can I do? how can I design lock-in amplifier and How can I get respond from ADA2200? Lastly I am sorry for my bad English. I hope you can understand me.
thank you for your interest
