9VRS4338DKLF

Overview

The Renesas 9VRS4338DKLF is an application-specific clock timing integrated circuit designed for Intel Atomic and PCI Express (PCIe) architectures. It features a maximum frequency of 200MHz and incorporates a Phase-Locked Loop (PLL). The device supports differential outputs with no differential input, operating on a supply voltage range of 1.05V to 1.5V. It is housed in a 48-VFQFPN package with dimensions of 6x6 mm and includes an exposed pad. The component is rated for an operating temperature range of 0°C to 70°C and utilizes surface mount technology.
