Product details
Overview
SIP5630CG-T1-E3 from Vishay is a 9-channel multimode SCSI bus active terminator IC that auto-selects single-ended (S/E) or low-voltage differential (LVD) termination, operates from 2.7 V to 5.25 V TERMPWR, meets SCSI-1 through SPI-4 (Ultra-320) standards, and features integrated SPI-3 mode change delay filtering for compliance without external capacitors - used in RAID disk arrays and enterprise storage backplanes.
For engineers reviewing the SIP5630CG-T1-E3 datasheet, SIP5630CG-T1-E3 pinout, SIP5630CG-T1-E3 application, or SIP5630CG-T1-E3 equivalent, key selection criteria include multimode S/E–LVD auto-detection, QSOP-36 thermal package compatibility, master/slave input support, hot-swap capability, and absence of HPD bus support.
Technical Context
The SIP5630CG-T1-E3 implements differential failsafe biasing and active negation logic to maintain SCSI bus signal integrity during arbitration and data phases. It senses bus mode via the DIFFSENS input and transitions between S/E and LVD termination states without external configuration.
Its internal thermal shutdown circuit protects against overtemperature conditions, and the DISABLE pin forces high-impedance bus state when asserted. The integrated SPI-3 mode change delay filter replaces the discrete 4.7-μF capacitor required by SPI-3 timing specifications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar SCSI bus termination applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI UCC5630A | Same 9-channel multimode function, identical QSOP-36 package, but lacks integrated SPI-3 delay filter | Requires external 4.7-μF capacitor for SPI-3 compliance; higher BOM cost and layout area | Select SIP5630CG-T1-E3 when eliminating discrete filter components is critical |

FAQ
What SCSI standards does the SIP5630CG-T1-E3 support?
The SIP5630CG-T1-E3 supports SCSI-1, SCSI-2, SPI-2 (Ultra-2), SPI-3 (Ultra-160), and SPI-4 (Ultra-320) standards. It does not support SPI-5 (Ultra-640) or HPD (high-power differential) SCSI buses. Its auto-detection logic ensures correct termination mode selection per active bus standard, and the SIP5630CG-T1-E3 datasheet confirms full compliance up to Ultra-320 timing and electrical requirements.
Does the SIP5630CG-T1-E3 require external components for SPI-3 compliance?
No. The SIP5630CG-T1-E3 integrates a mode change delay filter that satisfies SPI-3 (Ultra-160) timing requirements without an external 4.7-μF capacitor. This eliminates associated PCB area, cost, and reliability risks. The SIP5630CG-T1-E3 achieves this through on-die RC filtering, validated in Vishay's characterization reports and confirmed in the official product selection table.
How does the SIP5630CG-T1-E3 determine whether to use S/E or LVD termination?
The SIP5630CG-T1-E3 uses the DIFFSENS input pin to monitor bus voltage: ≤1.2 V triggers single-ended (S/E) termination, while >1.2 V activates low-voltage differential (LVD) termination. This auto-selection occurs dynamically and requires no software or external configuration. The SIP5630CG-T1-E3 maintains failsafe biasing in both modes and enters high-impedance state if DIFFSENS indicates HPD operation.
Is the SIP5630CG-T1-E3 compatible with hot-swap systems?
Yes, the SIP5630CG-T1-E3 is explicitly designed for hot-swap compatibility. It withstands live insertion and removal on powered SCSI backplanes without latch-up or bus contention. Its DISABLE pin and TERMPWR loss detection ensure graceful high-impedance entry during transition, and the SIP5630CG-T1-E3 thermal shutdown circuit prevents damage during transient overloads encountered in hot-swap events.
What is the role of the MS (Master/Slave) pin on the SIP5630CG-T1-E3?
The MS pin configures the SIP5630CG-T1-E3 as master (logic HIGH) or slave (logic LOW) in systems with multiple terminators, such as dual-controller RAID enclosures. In master mode, it drives termination bias; in slave mode, it defers to the master for coordinated control. This prevents conflicting bias currents and ensures deterministic bus behavior - a feature unique to SIP5630CG-T1-E3 and SIP5670 within the SiP56xx family.
