HMC835LP6GE Logic spec.

Hi all,

 

We wonder the logic specification of the HMC835.

 

Generally Logic voltage level @ CMOS,

Low : 0 V to 1/3 VDD

High : 2/3 VDD to VDD

;VDD = supply voltage

 

Following the Electrical Specifications @ the datasheet,

DVDD Digital supply, 3.3 V nominal

Logic Inputs
Vsw : 0.9 V (typ)

 

This means, each logic threshould voltage is,

Low : <0.9 V (typ) ?

High : >0.9 V (typ) ?

 

Is it correct ? 

We can not understand this spec.

 

Logic Outputs
VOH Output High Voltage : 1.8/3.3 V (typ) Why is it two voltage ? @ DVDD = 3.3 V.
VOL Output Low Voltage : 0 V (typ)

 

Best regards,

sss
