Hi Team,

is the CDCLVC1110 able to drive a 100CM tracelength at 40 MHz with 4mil traces with 4 mil spacing?

I recommend you try running SI simulations using CDCLVC11xx IBIS model with your PCB trace characteristics and receiver device.

Hi Alan,

I do not have a simulation tool that can run an SI simulation. is there any chance you can help to run it?

Hi Lucas,

Could you please provide the IBIS model for the receiver device and PCB trace characteristics (impedance or length, width, stackup)? This is needed for SI simulation.

Alan

HI Alan and Lucas,

the trace character can be described below:

1) trace 5mil x 35um x 1000mm (W x H x L);

2) trace to ground plane distance 0.1mm;

Thank you for the help.

Best regards,

Ron

Hi Alan,

the end device (DDC264CK) does not have an IBIS model, however its input pins have 4pF of load. is this sufficient to run the simulation?
