CDCLVC1102: VDD voltage range

Nam, Dino

Part Number: CDCLVC1102
Other Parts Discussed in Thread: LMK1C1102

Dear team, 

I found VDD specification like below at datasheet. This device is recommended using 2.5V or 3.3V supply. 

But, How about 2.8V VDD? Is this value is not available? Please let me know your opinion. 

if we can use 2.8V VDD, please let me know regarding input voltage range on 2.8V VDD like below. We can find only below data and Below specification is only for 2.5V or 3.3V VDD. 

Please review above request and let me know your opinion. 

Thank you.

    Hello Dino,

    CDCLVC1102 can be operated with 2.8V supply voltage. The 2.5V and 3.3V range was explicitly tested during characterization for all parameters, therefore it is in the datasheet.

    For the VIL/VIH values you can use VDD/2 +/-400mV.

    We also have a newer version of that device LMK1C1102. this comes in 2 package options. Same rule applies here too. VIL/VIH is 0.2*VDD and 0.8*VDD.

    Regards,

    Julian
