Active SCSI Terminator

Micro Linear Corporation 

ML6509

This is a very important characteristic that the terminator

helps overcome by increasing the noise margin and

boosting the step as high as possible. This capability for

the ML6509 implementation is illustrated in the attached

simulation graphs which show the terminator performance

under different cable impedance situations and a

comparison is shown with the standard Boulay terminator,

under identical conditions.
