ADL5565 IMD3 performance with narrower spacing

Question asked by gavint on Jul 7, 2015

I am looking for some assistance on the ADL5565 ADC driver.


The datasheet specifies the ADL5565 IMD3 performance at 200MHz with Av = 6dB, RL = 200R, Vout = 2 V p-p composite as -96dBc.

What frequency spacing is this tested at? The IMD2 frequency spacing is given as 2MHz - is this the same for the IMD3?


Lastly, are there any documented results for IMD3 testing at 200MHz with a 200kHz spacing?
