easing system design. They can drive both source-terminated and doubleterminated 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.
