CDC3S04: A4 pin in IBIS model

Cedrick

Part Number: CDC3S04

Hi,

Good day.

Our customer is using the IBIS model for the CDC3S04 and they noticed that the pin A4 (CLK1 pin) gives an option only for input. On the datasheet this should be an output pin. Can you please help us provide the correct IBIS model for the customer? Thank you for your support.

Regards,

Cedrick

Hi Cedrick,

This issue was recently brought to our attention. A typical IBIS model wouldn't make sense for this output because the output swing is dependent on the input swing, thus the output doesn’t have defined VI-characteristics for logic hi/lo inputs.

Kind regards,
Lane
