- Differential output architecture ensures precise impedance matching across all 14 SCSI signal lines for reliable data transfers
- 48-pin LQFP package with 0.5 mm pitch enables compact PCB footprint in storage controller and server designs
- Single-device solution replaces multiple discrete termination resistor networks, simplifying BOM and reducing board area
Applications
The UCC5628FQPG4 is used in SCSI storage systems including disk arrays, tape drives, and server backplane designs where proper bus termination is critical to prevent signal reflections at high data rates. It is well-suited for embedded storage controllers and industrial data acquisition systems requiring reliable SCSI bus signal integrity. The device simplifies termination design by integrating all 14 SCSI lines into a single compact package.

Frequently Asked Questions
How many signal lines does the UCC5628FQPG4 terminate?
The UCC5628FQPG4 terminates 14 SCSI bus signal lines simultaneously. This single-device integration eliminates the need for multiple discrete termination resistor networks, simplifying PCB design and reducing component count in SCSI storage systems.
What package does the UCC5628FQPG4 use?
The UCC5628FQPG4 is housed in a 48-pin LQFP (Low-Profile Quad Flat Package) with a 0.5 mm lead pitch, designated JESD-30 code S-PQFP-G48. This surface-mount package provides a compact 20 x 20 mm footprint suitable for high-density PCB layouts in server and storage controller boards.
Is the UCC5628FQPG4 RoHS compliant?
The UCC5628FQPG4 is listed with Pbfree Code: No, indicating it is not a lead-free (RoHS) version. Designers requiring lead-free compliance should check with Texas Instruments for alternative part numbers or updated versions that meet RoHS and JESD-609 e4 requirements.
What type of SCSI termination does the UCC5628FQPG4 provide?
The UCC5628FQPG4 provides active SCSI bus termination with differential outputs across all 14 signal lines. Active termination dynamically regulates termination voltage for better noise margins compared to passive resistor termination, making it suitable for high-speed SCSI interfaces such as Ultra2 and Ultra3 SCSI operating at 40 to 80 MB/s.
