9ZX21901BKLFT

The 9ZX21901BKLFT from Renesas is a high-performance application specific clock buffer IC specifically designed for Intel QPI and PCI Express interfaces. It integrates a Phase-Locked Loop (PLL) to generate low-jitter clock signals with a differential HCSL output at a frequency of 400MHz. The device accepts clock inputs and provides a 2:19 input-to-output ratio, making it suitable for distributing clock signals in advanced computing and networking systems.

The IC operates from a supply voltage range of 3.135V to 3.465V and is specified for operation over a temperature range of 0°C to 70°C. It is housed in a compact 72-VFQFN Exposed Pad package (supplier device package 72-VFQFPN 10x10 mm) and is designed for surface mount assembly. The differential input and output capability ensures robust signal integrity in high-speed digital environments.

This component is ideal for applications requiring precise clock generation and distribution for PCIe and QPI buses, commonly found in servers, workstations, and high-performance computing platforms. The RoHS compliance (unverified) and MSL level 1 rating indicate compatibility with standard lead-free soldering processes.
