Dear Sir,
Sorry for the delayed reply.
I tried you suggestion but it is not working. I did the following:-
1. I connected the Board with Battey supply.
2. I took another supply and connected it to the ctrl pin, 2.2 volt was applied constanly to the ctrl pin.
3. In labview I pressed Programm. It shows the correct frequency immediately.
4. Everything was disconnected and Restarted .further on toggling the control pin .it again starts the freqency from 250 khz,and goes upto 7 mhz. it keeps on changing value it does not stop.
5. Till it is connected to the Computer it works fine as soon as you disconnect and run independently it does not work.
Note:- i have been giving 2.3 volt ,Boards was set to be toggled from hardware not software.
Request you to advice what to do next.
Regards,
Rahul Vijay
