SIP5670CG-T1-E3

Overview

The SiP5670CG-T1-E3 is a SCSI bus active terminator IC from the Vishay Siliconix SiP56xx family, designed for 9-channel termination. It supports S/E and LVD modes with automatic selection via the DIFFSENS signal. 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 and meets SCSI-1 through SPI-4 standards. The component is housed in a QSOP-36 lead-free package and operates over a temperature range of 0°C to +70°C.

Feature Summary

• Automatic switching between single-ended (S/E) and low-voltage differential (LVD) termination modes based on bus state sensing.
• Integrated SPI-3 mode change delay filter eliminates the need for external bulky capacitors.
• Includes master/slave input capability and status indicator functions.

Applications

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

Procurement Notes

Verify the specific suffix CG against official documentation to confirm package type and tape-and-reel configuration. Confirm RoHS compliance status as indicated by the E3 suffix. Check current availability and lifecycle status directly with Vishay or authorized distributors, as this component may be subject to discontinuation or limited supply constraints.

Selection Notes

Select the SiP5670CG-T1-E3 when a 9-channel active terminator is required for SCSI buses supporting up to Ultra 320 speeds. Ensure the design accommodates the 2.7-V to 5.25-V power supply range. Verify that the application does not require HPD support, as the device enters high impedance mode under those conditions. Consider the integrated delay filter if SPI-3 timing compliance is necessary without external components.

Part Context

This part belongs to the SiP56xx family of SCSI active terminators, which also includes variants like the SiP5630, SiP5668, and SiP5696. These devices share common features such as auto S/E-LVD selection and thermal protection but differ in channel count, package type, and specific standard support levels.

Replacement Considerations

Publicly confirmed alternate sources listed for the SiP5670 include TI UCC5670 and Maxim DS2127. Verify pin compatibility and electrical specifications before substitution.
