DS160PR822NJXT

Signal Buffers, Repeaters, Splitters Overview

The DS160PR822NJXT is an eight-channel linear redriver designed for PCIe 4.0 and UPI 2.0 interfaces operating at data rates up to 16 Gbps. It features four 2x2 crosspoint mux functions and continuous time linear equalizers (CTLE) providing up to 18 dB of boost at 8 GHz to handle channels with up to 42 dB loss. The device operates on a single 3.3 V supply, consuming 107 mW per channel, and includes an ultra-low latency of 90 ps. It supports pin-strap, SMBus/I2C, or EEPROM programming and functions within an industrial temperature range of –40°C to 85°C in a 64-pin WQFN package measuring 5.5 mm × 10 mm.

Signal Buffers, Repeaters, Splitters Feature Summary

• Protocol agnostic linear redriver supporting PCIe 4.0, UPI 2.0, SAS, SATA, DisplayPort, and XFI.
• Integrated quad 2x2 crosspoint mux function selectable via pin control or SMBus/I2C.
• Continuous time linear equalizer (CTLE) provides high-frequency boost to open closed input eyes caused by inter-symbol interference.
• Internal linear voltage regulator supplies clean power to high-speed datapaths for high immunity to board supply noise.
