TLK6201EA: Can not detect SAS OOB

Part Number: TLK6201EA
Other Parts Discussed in Thread: SN75LVCP600

Hi 

We encountered an issue that TLK6201EA not able to detect SAS OOB signal due to the SAS OOB signal level under the voltage threshold. May i have your suggestion 

1. is there any way to lower down the detect threshold so my SAS OOB 1.5G/3Gbps signal can be detected ? 

2. If TLK6201EA can not do this, is there any other suggested Equalizer/repeater that has LOS (Loss of Signal Detection) ?

    Hi.

    The signal detect (LOS) propagation delay of 20ns will likely cause SATA/SAS OOB information to be rejected at the system level for active pulse times < the specified minimum.

    For most SATA applications I would recommend the SN75LVCP600.
