DS160PR810NJXR

Signal Buffers, Repeaters, Splitters Overview

The DS160PR810NJXR is an eight-channel linear redriver designed for PCIe 4.0 applications up to 16 Gbps. It operates on a single 3.3 V supply with a maximum active power of 107 mW per channel and supports an industrial temperature range from -40°C to +85°C. The device features a continuous-time linear equalizer (CTLE) providing up to 18 dB boost at 8 GHz, handling up to 42 dB of channel loss. Key electrical parameters include a propagation delay of 90 ps, additive random jitter of 70 fs, and a maximum SMBus clock frequency of 303 kHz. It is housed in a 64-pin WQFN package measuring 5.5 mm by 10 mm.
