Silicon Standard SS8218

The SS8218 Multi-mode LVD/SE SCSI terminator provides a smooth transition to the next generation of the SCSI Parallel Interface (SPI-3). It automatically senses the bus, via DIFFSENS, and switches the termination to either single-ended (SE) or low voltage differential (LVD) SCSI, dependent on which type of devices are connected to the bus. For a 16-bit Wide SCSI bus to be operational, three SS8218 terminators are needed.

GENERAL DESCRIPTION

If the SS8218 detects a HVD SCSI device, it switches to a high impedance state. The Multi-mode terminator contains all functions required to terminate and auto detect and switch modes for SCSI Parallel Interface (SPI) bus architectures. For the SE termination, one regulator and nine precision 110ohm resistors are used. For the LVD termination, the SS8218 integrates 18 regulated supplies with nine precision resistor strings. or LVD Termination Meets SCSI-1, SCSI-2, SCSI-3 SPI Ultra (Fast-20), Ultra 2(SPI-2 LVD), Ultra160 (SPI-3 LVD) standards. Supports active negation 3pF channel capacitance Thermal protection Hot-swap compatible 5% tolerance on SE and LVD termination resistance 28 and 36 pin SSOP package 28 Pin SSOP: Pin Compatible with DS2119 36 Pin SSOP: Pin Compatible with DS2118, LX5241 and UCC5630
