Other Parts Discussed in Thread: THS4151, ADS54J60
Hello,
We are using the ADS54J40EVM board to evaluate our design - Our board is connected to it.
1. We want to operate the board so the input will be Differential DC coupling. We drive the board through differential driver - THS4151. (see attached schematics)
2. When the input to THS4151 is a DC voltage - for example 3V - the ADC is oscillate at 245.76Mhz (see attached) ( ADC clock is 983.04 Mhz).
What is wrong with our connection? What should we do in order to work differential DC coupled to the ADC?
Regards,
Giora
