The RC190xx (RC19024, RC19020, RC19020A072, RC19016, RC19013, RC19008, RC19004, and RC19002) ultra-high performance fanout buffers support PCIe Gen1-7. They provide a Loss-Of-Signal (LOS) output for system monitoring and redundancy. The devices also incorporate Power Down Tolerant (PDT) and Flexible Startup Sequencing (FSS) features, easing system design. They can drive both source-terminated and double-terminated loads, operating up to 400MHz.

The family offers 2, 4, 8, 13, 16, 20, and 24 LowPower (LP) HCSL output pairs in 3 × 3 mm to 10 × 10 mm packages. The RC190xx devices offer higher output counts in smaller packages compared to earlier buffer families. The buffers support both Common Clock (CC) and Independent Reference (IR) PCIe clock architectures.
