The Texas Instruments DS320PR810NJXT is an eight-channel, low-power, high-performance linear redriver designed to improve signal integrity in high-speed serial interfaces. It supports PCI Express 5.0 data rates up to 32Gbps, along with CXL 2.0, UPI 2.0, and other compatible high-speed interface applications.
The device integrates continuous-time linear equalization (CTLE) with programmable high-frequency boost to help compensate for channel loss and inter-symbol interference caused by PCB traces and other interconnects. Its linear signal path preserves transmitter preset characteristics and supports PCIe link training, making it suitable for systems with demanding bandwidth, latency, and signal integrity requirements.
The DS320PR810NJXT operates from a single 3.3V supply and supports configuration through pin strapping, SMBus, or an external EEPROM. It is housed in a 64-pin WQFN package measuring 5.5mm × 10mm, making it suitable for servers, data centers, high-performance computing, storage systems, and high-speed expansion platforms.
