Our customer is going to use HMC921LP4E by different supply voltage to VCC1 and VCC2. Are there any problem in case of VCC2 < VCC1 (e,g, VCC2=5V, VCC1=4.7V)? If OK, how much different voltage can be acceptable?
We have not tested HMC921 with Vcc1 level different than Vcc2. But 1 V difference between Vcc1 and Vcc2 should not be a problem.
Thank you for your answer.
Thanks & Regards,
