• Manufacturer Part Number: ml6509
• Description: Active Scsi Terminator
• Manufacturer: Microsemi 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.
