Renesas Electronics RC190x Fanout Buffers

Renesas Electronics RC190x Fanout Buffers are ultra-high performance fanout buffers supporting PCIe Gen5 and Gen6. These buffers provide a Loss-Of-Signal (LOS) output for system monitoring and redundancy. The RC190x buffers feature Power Down Tolerant (PDT), Flexible Startup Sequencing (FSS), and Automatic Clock Parking (ACP) upon loss of CLKIN. These fanout buffers drive source-terminated and double-terminated loads up to 400MHz. The RC190x buffers support Common Clock (CC) and Independent Reference (IR) PCIe clock architectures. The buffers offer 4, 8, 13, 16, 20, and 24 Low-Power (LP) HCSL output pairs in 4mm x 4mm to 10mm x 10mm packages. Typical applications include cloud/high-performance computing, nVME storage, networking, and accelerators.
