SN75LVCP601: SN75LVCP601 trace length

Part Number: SN75LVCP601

Hi

Can yo help to explain what is that mean in datasheet?

 1. Does it mean the trace length at lease need 3 inches before input to LVCP601?

2. the cap should place near to LVCP601 or SATA connector or in the middle?

    Hi Eric,

    1. Very short input traces can compromise the equalizer output, even at lower gain levels.  It is recommended to have a minimum of 3 inches of trace to the Rx inputs.

    2. The capacitor placement is not critical, but I recommend to keep it in the middle or at the connector to avoid possible reflections between the capacitor and the LVCP601 impacting the signal quality.  Adding a GND relief (hole in the reference plane) immediately below the capacitor footprint can help to minimize any impedance change and improve overall eye opening.

    Regards,
