LMK5C33216RGCR

Clock Generators, PLLs, Frequency Synthesizers Overview

The LMK5C33216 is an ultra-low jitter clock synchronizer designed for wireless communications with BAW technology. It features three digital phase-locked loops (DPLLs) paired with analog phase-locked loops (APLLs). The device provides 16 programmable outputs supporting LVPECL, LVDS, HSDS, CML, and LVCMOS formats. APLL3 utilizes Bulk Acoustic Wave VCBO technology to achieve 40 fs RMS jitter at 491.52 MHz. It operates on a single 3.3-V supply with internal LDOs and supports I²C or SPI interfaces.
