ML6518 - 18 Line Hot-Insertable Active SCSI Terminator

General Description

The ML6518 BiCMOS 18 line SCSI terminator provides active termination in SCSI systems using single-ended drivers and receivers.

Active SCSI termination helps to effectively control analog transmission line effects such as ringing, noise, crosstalk, and ground bounce.

Key Features

  • s s s s s s s s s Fully monolithic IC solution providing active termination for 18 lines of the SCSI bus Provides onboard support for hot-insertability on the SCSI bus Low dropout voltage (1V) linear regulator, trimmed for accurate termination current Low disconnect capacitance (typically < 5pF) Logic pin with active pull-up to disconnect terminator from the SCSI bus Current sinking capability in excess of 8.3mA per line to handle active negation driver overshoots above 2.85V Negative clamping.

August 2000 ML6518* 18 Line Hot-Insertable Active SCSI Terminator GENERAL DESCRIPTION The ML6518 BiCMOS 18 line SCSI terminator provides active termination in SCSI systems using single-ended drivers and receivers. Active SCSI termination helps to effectively control analog transmission line effects such as ringing, noise, crosstalk, and ground bounce. In addition, the ML6518 provides support for hot insertability on the SCSI bus. The ML6518 provides a V-I characteristic optimized to minimize transmission line effects during both signal negation and assertion using a MOSFET-based architecture. The desired V-I characteristic is achieved by trimming one resistor in the control block.
