My customer has questions about the power of HMC68x series(ex:HMC686, HMC687.....).
1. In the datasheet, there are the graphics which VCC1,2,3 = 3.3V is used for low power consumption as shown below.
What is the effective power range of HMC68x ?
2. Should the customer wants, is it possible to use VCC1,2,3 = 4.5V ?
The effective supply voltage for this part is 3.3V to 5V. 4.5V should be fine. The performance will not be exactly the same as datasheet if applying lower voltage. There will be trade offs between power consumption and performance.
