CMOS logic as the output standard of AD9554

miladmazi on Feb 22, 2017

Hello,

I'm working with the EVAL-AD9554 board as jitter cleanup for my high-precision ADC (AD7760 with 24 bits). I was wondering if there is a way to get CMOS logic from clock outputs? Actually, I need 0 to 3.3 V clock to feed the AD7760. As I searched on the main web page for EVAL-AD9554 there was no documentation or application note about its configurations and that's why I'm confused. It would be highly appreciated if anybody can help me in this matter. Thanks

Hi,

The AD9554 does not support 3.3V CMOS on it's outputs, it is a 1.8V device. Table 8 of the datasheet lists the output driver swings for the different modes.

The AD9559 is a dual version of the…

The AD9559 is a dual version of the AD9554 which supports 3.3V CMOS outputs. However, please note that only outputs 0B and 1B support a 3.3V CMOS logic format.
