Frequently Asked Questions
How many SCSI signal lines does the UC5601DWPG4 terminate, and why does this matter for multi-device bus configurations?
The UC5601DWPG4 provides active termination for 18 SCSI signal lines in a single 28-pin SOIC package. Terminating all 18 lines simultaneously prevents signal reflections at the bus endpoints, which is essential for reliable high-speed data transfers in multi-device SCSI chains where unterminated lines cause bit errors.
What package does the UC5601DWPG4 use and how does it fit into standard PCB assembly workflows?
The UC5601DWPG4 is housed in a 28-pin SOIC package (JESD-30 code R-PDSO-G28) with a 0.4-inch body width and standard SOP28 pin pitch. This format is compatible with automated SMT pick-and-place and reflow soldering processes, simplifying integration into standard PCB assembly lines for storage controller boards.
Is the UC5601DWPG4 a suitable choice for new SCSI-based industrial storage designs, given its end-of-life status?
The UC5601DWPG4 carries a YTEOL of 0, indicating end-of-life status, which means procurement teams should plan for last-time-buy quantities or identify alternative SCSI terminators with 18-bit capacity. For new designs, engineers may prefer actively supported terminators; existing systems maintaining 18-signal-line SCSI buses may still source this part through distributor excess inventory.
What design advantage does active termination in the UC5601DWPG4 provide over passive resistor network terminators on SCSI buses?
Active termination in the UC5601DWPG4 regulates the termination voltage to a precise level across all 18 signal lines, maintaining SCSI bus signal levels over a wider range of supply variations compared to passive resistor networks. This keeps bus voltage within SCSI specification windows, reducing noise margins and improving reliability at SCSI bus clock rates above 10 MHz.
