SIP5630CG-T1-E3

Overview

The Vishay Siliconix SiP5630CG-T1-E3 is a SCSI bus active terminator IC designed for 9-channel configurations. It supports S/E and LVD termination modes, meeting SCSI-1, SCSI-2, SPI-2 (Ultra-2), SPI-3 (Ultra-160), and SPI-4 (Ultra-320) standards. The device operates within a 2.7-V to 5.25-V TERMPWR range and includes master/slave input functionality. It features an integrated SPI-3 mode change delay filter option and differential failsafe bias. The component utilizes a QSOP-36 lead-free package and is rated for operation between 0°C and +70°C.

Feature Summary

• Auto selection of S/E or LVD SCSI termination
• Master/slave input capability
• Integrated SPI-3 mode change delay filter option
• Hot swap compatible design

Applications

• Disk array (RAID)
• Storage area networks (SAN)
• Network attached storage (NAS)
• SCSI cable systems
• Server and workstation architectures

Procurement Notes

Verify the specific suffix 'CG' against official documentation to confirm package type and temperature rating variations. Confirm end-of-life status through manufacturer notifications before finalizing procurement plans. Ensure compatibility with existing system power rails and SCSI bus standards during integration.

Selection Notes

Select this component for 9-channel SCSI applications requiring multimode support. Verify that the system does not utilize HPD buses, as the device enters high impedance mode in such scenarios. Consider alternative family members like the SiP5670 if additional channels or different packaging options are required for the specific board layout constraints.

Part Context

This part belongs to the SiP56xx family of SCSI bus active terminators. It serves as a functional replacement for legacy components such as the TI UCC5630A and Maxim DS2118. The family provides standardized termination solutions for various SCSI operational modes, ensuring signal integrity across parallel SCSI interfaces.

Replacement Considerations

Public confirmed substitutes include the TI UCC5630A and Maxim DS2118. Verify pinout compatibility and electrical specifications before substitution. Check for any differences in operating voltage ranges or package dimensions.
