CDCLVC1104: CLKIN voltage level conditions

JH Shin

Part Number: CDCLVC1104

Hello,

According to the CDCLVC1104 datasheet, when VDD is 3.3V, the input voltage level conditions for the CLCLVC1104 are below.

When VDD is 3.3V, is it correct to input the clock to CLKIN only within the range of VIL and VIH as below?

- VIL = GND ~ 1.05V

- VIH = 2.25V ~ 3.8V

If the CDCLVC1104 user inputs a clock signal with a level out of this range to CLKIN, is there a problem?

Thank you.

Hi JH,

if the input signal is outside the absolute maximum ratings damage could occur.

What signal level do you want to apply to the device?

Regards,

Julian

Hi Julian,

The customer said they wanted to clarify the voltage level specifications of CLKIN for quality management.

They will allow the clock signal to be supplied within the limits below.

- VIL = GND ~ 1.05V

- VIH = 2.25V ~ 3.8V
