UCC5629  
Multimode SCSI 14 Line Terminator  
DESCRIPTION  
FEATURES  
The UCC5629 Multimode SCSI Terminator provides a smooth transition  
into the next generation of the SCSI Parallel Interface (SPI-2). It automati-  
cally senses the bus, via DIFFB, and switches the termination to either sin-  
gle ended (SE) or low voltage differential (LVD) SCSI, dependent on which  
type of devices are connected to the bus. The UCC5629 can not be used  
on a HVD, EIA485, differential SCSI bus. If the UCC5629 detects a HVD  
SCSI device, it switches to a high impedance state.  
Auto Selection Single Ended (SE) or  
Low Voltage Differential (LVD)  
Termination  
Meets SCSI-1, SCSI-2, SCSI-3, SPI,  
Ultra (Fast-20), Ultra2 (SPI-2 LVD)  
and Ultra3 Standards  
2.7V to 5.25V Operation  
Differential Failsafe Bias  
The Multimode terminator contains all functions required to terminate and  
auto detect and switch modes for SPI-2 bus architectures. Single Ended  
and Differential impedances and currents are trimmed for maximum effec-  
tiveness. 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 perform-  
ance analog functions necessary to implement SPI-2 termination in a sin-  
gle monolithic device.  
Thermal packaging for low junction  
temperature and better MTBF.  
Reversed Polarity Disconnect  
The UCC5629 is offered in a 48 pin LQFP package for a temperature range  
of 0°C to 70°C.
