DS64BR401SQE/NOPB

Signal Buffers, Repeaters, Splitters Overview

The DS64BR401SQE/NOPB is a quad bi-directional repeater manufactured by Texas Instruments, designed for high-speed signal integrity in data center environments. It operates at a fixed supply voltage of 2.5 V with a maximum operating current of 380 mA and power dissipation of 4.21 W. The device supports a maximum clock frequency of 100 kHz and functions within an ambient temperature range of -10°C to +85°C. Housed in a 54-pin WQFN package suitable for surface mount technology, it addresses front port, backplane, and peripheral I/O applications.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the complete part number including the suffix NOPB to ensure compliance with lead-free manufacturing standards and specific packaging configurations. Confirm that the 2.5 V supply requirement aligns with the target system design before procurement. Check for moisture sensitivity handling requirements due to the WQFN package type during storage and assembly processes.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when a quad-channel solution is required for bidirectional signal buffering at data rates supported by the specified 100 kHz clock interface. Ensure the design accommodates the 2.5 V single-supply constraint and the thermal dissipation capabilities of the WQFN-54 package. Evaluate board space constraints against the physical dimensions of the 54-terminal footprint.
