Overview
The DS160PR410RNQT is a four-channel linear redriver designed for PCI Express Gen 4 applications. It supports data rates up to 25 Gbps per channel, ensuring signal integrity over lossy channels. The device operates on a single 3 V to 3.6 V power supply and draws approximately 150 mA of current. It features an input capacitance of 1.5 pF and a propagation delay of 70 ps. The component is housed in a 40-pin WQFN package measuring 6x4 mm. It functions within a temperature range of -40°C to +85°C and includes I2C interface capabilities for configuration.
Feature Summary
- Four-channel architecture supporting high-speed serial data transmission
- Linear redriver topology optimized for PCIe Gen 4 signal conditioning
- Integrated I2C interface for device control and monitoring
- Low input capacitance to minimize signal loading effects
Applications
- PCI Express Gen 4 backplane interconnects
- Front panel connectivity solutions
- Active cable systems requiring signal regeneration
Procurement Notes
Verify the specific suffix RNQT against the official Texas Instruments datasheet to confirm the tape and reel packaging quantity and moisture sensitivity level. Ensure the ordering part number matches the required operating temperature range and package variant. Cross-reference with authorized distributors to confirm current availability status and lead times, as supply chain conditions may vary.
Selection Notes
Select this component when designing for PCI Express Gen 4 interfaces requiring linear signal restoration rather than retiming. Compare input capacitance and power consumption against alternative redrivers to ensure compatibility with system power budgets. Verify that the 40-WQFN package dimensions fit the PCB layout constraints and thermal requirements of the target application environment.
Part Context
This device belongs to the DS160PR410 family of signal buffers and repeaters from Texas Instruments. It is distinct from retimer devices like the DS250DF410, which offer clock recovery capabilities. The RNQT suffix indicates a specific commercial-grade temperature range and packaging option within the broader product line.
Replacement Considerations
Direct substitutes include other DS160PR410 variants such as DS160PR410RGFTQ1 for automotive qualification or different packaging options like DS160PR410RNQR. Evaluate pin-to-pin compatibility and electrical parameter equivalence before substitution.
