The UCC5686PM from Texas Instruments is a high-performance single-ended SCSI (Small Computer System Interface) terminator designed for Ultra SCSI applications. This integrated circuit is essential for ensuring signal integrity in SCSI bus systems by matching the impedance of the bus to prevent reflections that can cause data errors.
Key Features
- Compatibility: The UCC5686PM is designed to be compatible with Fast-20 and Ultra SCSI (SCSI-3) standards, providing broad support for a range of SCSI devices.
- Active Termination: It features active termination, which includes a precision voltage regulator to provide stable termination voltages, ensuring reliable communication over the SCSI bus.
- Channel Configuration: The terminator supports up to 9 data lines, which is typical for an 8-bit SCSI bus, and includes additional termination for control and parity lines.
- Power Dissipation: With its low power consumption design, the UCC5686PM helps to minimize power dissipation on the bus.
- Package: The device is offered in a 28-pin molded lead-frame package, which is designed for surface mounting and is suitable for high-density SCSI cards.
Applications
The UCC5686PM is ideal for a variety of applications where reliable data transfer over a SCSI bus is required. This includes, but is not limited to, server storage systems, RAID arrays, SCSI disk drives, and SCSI host adapters.
