Renesas Electronics RC1910x PCIe Gen7 Clock Buffers

Renesas Electronics RC1910x PCIe Gen7 Clock Buffers are PCIe Gen7, 1.8V ultra-high performance fanout buffers. These buffers feature Loss-Of-Signal (LOS) output for system monitoring and redundancy. The RC1910x buffers include Power Down Tolerant (PDT) and Flexible Startup Sequencing (FSS). These clock buffers offer 2, 4, or 8 Low-Power (LP) HCSL output pairs in 3 x 3, 4 x 4, and 5mm x 5mm packages. The RC1910x buffers provide pin or SMBus selectable 33Ω, 85Ω, or 100Ω differential output impedance and pin or SMBus selectable output slew rate. Typical applications include cloud/high-performance computing, nVME storage, networking, and AI accelerators.
