RC19004A100GNL#BB0

RC190xx is a PCIe gen5/6 fan-out buffer family with loss-of-signal indication. The RC190xx ultra-high performance fan-out buffers support PCIe Gen5 and Gen6. They provide a Loss-Of-Signal (LOS) output for system monitoring and redundancy. The devices also incorporate Power Down Tolerant (PDT) and Flexible Start-up Sequencing (FSS) features, easing system design. They can drive both source terminated and double terminated loads, operating up to 400MHz. The RC190xx devices offer higher output counts in smaller packages compared to earlier buffer families. It has low additive phase jitter (PCIe Gen5 additive phase jitter: 6fs RMS and PCIe Gen6 additive phase jitter: 4fs RMS). High-speed serial interface (SBI) supports output enable and device daisy-chaining. Extended operating temp provides robust thermal confidence. Applications include cloud/high-performance computing, nVME storage, networking, accelerators, computing and industrial.
