932SQ420DGLFT

Application Specific Clock/Timing Overview

The Renesas 932SQ420DGLFT is a clock synthesizer IC designed for Intel Romley server architectures. It features a single PLL circuit with one input and nineteen outputs, providing a 1:19 frequency ratio. The device accepts a crystal input and generates HCSL differential outputs. It operates within a supply voltage range of 3.135V to 3.465V and supports maximum frequencies up to 146.7MHz. The component is housed in a 64-TFSOP package with a width of 6.10mm and functions reliably across an industrial temperature range of 0°C to 70°C.
