SS8219G

Ultra320 Multi-mode LVD/SE SCSI Terminator

PRODUCT SUMMARY

DESCRIPTION

The SS8219G multi-mode LVD/SE SCSI terminator

provides a smooth transition between modes of the

SCSI Parallel Interface. It automatically senses the bus

via DIFFSENS and switches the termination to either

single-ended (SE) or low voltage differential (LVD) SCSI,

based on which type of devices are connected to the bus.

If the SS8219G detects an HVD SCSI device, it switches

to a high impedance state.

SPI mode auto-detection/switching.

Pin/pin compatible with popular industry

standard parts DS2118/9 and UCC5672

FEATURES

Auto-selectable single-ended or LVD termination

Meets SCSI-1, SCSI-2, SCSI-3 SPI Ultra (Fast-20),

Ultra 2 (SPI-2 LVD), Ultra160 (SPI-3 LVD)

and Ultra320 (SPI-4 LVD) standards

Supports active negation

Channel capacitance of 3pF

Operation from 2.9V to 5.5V

Thermal protection

Hot-swap compatible

Tolerance of 5% on termination resistance

Available in 28 pin TSSOP or 36 pin SSOP

A 16-bit wide SCSI bus requires three SS8219G for

termination.

This multi-mode terminator contains all the functions

to terminate, auto detect and switch modes for SCSI

Parallel Interface (SPI) bus architectures.

For SE termination, one regulator and nine precision 110W

resistors are used.

For LVD termination, the SS8219G integrates 18 regulated

supplies with nine precision resistor strings.

Pb-free, RoHS compliant.

APPLICATIONS

High performance data storage systems in servers,

workstations, high-end and industrial PCs, and RAID

disk arrays.
