CDCDB803: Questions about the Clock input/output circuit configuration of CDCDB803.

Hi,

I have the below question about cdcdb803 .

1. How should the circuit of the CLKIN pin be configured when a 3.3V level cmos single-ended signal is used as an input?

2. How should the circuit of the CK0~CK7 output pins be configured when using the output signals to be compatible with LVDS?

Thanks,

    Hello,

    1. The CDCDB803 only accepts LP-HCSL inputs. To convert the CMOS signal for a differential input, please use the following termination.

    2. The CDCDB803 only outputs LP-HCSL outputs. To convert the output to LVDS, please use the following termination.
