9ZX21501BKLFT

Overview

The Renesas Electronics Corporation 9ZX21501BKLFT is a single-circuit Intel QPI and PCI Express (PCIe) fanout buffer. It features a 1:15 input-to-output ratio with differential HCSL signaling on both input and output sides. The device incorporates an internal Phase-Locked Loop (PLL) and supports maximum frequencies up to 400MHz. It operates within a supply voltage range of 3.135V to 3.465V and functions at temperatures between 0°C and 70°C. The component is housed in a 64-VFQFPN package measuring 9x9mm with an exposed pad, designed for surface mount installation.
