Overview
The DS100BR410SQ/NOPB is a four-channel low-power redriver manufactured by Texas Instruments, designed for high-speed serial data transmission. It supports data rates up to 10.3 Gbps and operates on a single 2.5 V supply voltage with a typical current consumption of 104 mA. The device features CML input and output interfaces, providing signal integrity through input equalization and output de-emphasis capabilities. With a propagation delay of 240 ps and an input capacitance of 10 pF, it is housed in a 48-WQFN package measuring 7x7 mm. The component is rated for operation within a temperature range of -40°C to 85°C and is specifically intended for SATA applications.
Feature Summary
- Four-channel architecture supporting simultaneous high-speed data processing
- Integrated input equalization and output de-emphasis for signal integrity maintenance
- Low power consumption design optimized for thermal efficiency
- CML interface compatibility for seamless integration with source-synchronous systems
Applications
- SATA storage interfaces
- Front port connections
- Backplane interconnects
- Peripheral I/O expansion
Procurement Notes
Verify the complete part number including the suffix NOPB to ensure lead-free compliance and specific packaging configuration. Confirm the 48-WQFN package dimensions match the PCB footprint requirements. Check moisture sensitivity level (MSL 3) handling procedures if the component has been exposed to ambient conditions beyond the specified timeframe prior to soldering.
Selection Notes
Select this component when a four-channel solution is required for SATA or similar 10.3 Gbps applications. Ensure the system design accommodates the 2.5 V supply rail and CML signaling levels. Compare against the two-channel DS100BR210 if fewer lanes are sufficient, or consider retimer options like the DS100RT410 if clock recovery is necessary rather than simple redriving.
Part Context
This device belongs to the DS100BR series of signal buffers and repeaters from Texas Instruments. It complements other members such as the DS100BR210 (two-channel) and the DS100RT410 (retimer). The series focuses on extending reach and maintaining signal quality in high-speed digital interfaces without requiring complex clock management.
Replacement Considerations
Publicly confirmed substitute part numbers were not identified in the provided documentation. Verify pin-to-pin compatibility with any alternative vendors independently.
