多模式SCSI 9号线终结者 Multimode SCSI 9 Line Terminator

DESCRIPON

The UCC5630A Multimode SCSI Terminator provides a smooth transition into the LVD SCSI Parallel Interface SPI-2, SPI-3, SPI-4. It automatically senses the bus, via DIFFB, 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. The UCC5630A can not be used on a HVD, EIA485, differential SCSI bus. If the UCC5630A detects a HVD SCSI device, it switches to a high impedance state.

The Multimode terminator contains all functions required to terminate and auto detect and switch modes for SPI-2, SPI-3 and SPI-4 bus architectures. Single Ended and Differential impedances and currents are trimmed for maximum effectiveness. Fail Safe biasing is provided to insure signal integrity. Device/Bus type detection circuitry is integrated into the terminator to provide automatic switching of termination between single ended and LVD SCSI and a high impedance for HVD SCSI. The multimode function provides all the performance analog functions necessary to implement SPI-2 termination in a single monolithic device.

The UCC5630A is offered in a 36 pin SSOP package, as well as a 48 pin LQFP package for a temperature range of 0°C to 70°C.
