The product is a 12-output clock generator with an integrated 2.0 GHz VCO, low phase noise, phase-locked loop, and can accept 250MHz reference signals.
The AD9517-3 is a 12‑output clock generator that integrates a 2.0 GHz VCO and PLL, targeting low‑jitter, low‑phase‑noise distribution for high‑speed data converters, wireless transceivers, and instrumentation. It supports an on‑chip VCO (1.75‑2.25 GHz) or an optional external VCO/VCXO up to 2.4 GHz.
Key features include four LVPECL outputs (up to 1.6 GHz), four LVDS outputs (up to 800 MHz), eight CMOS outputs (up to 250 MHz), programmable dividers, fine‑delay adjustment, and a serial control port. The device operates from a single 3.3 V supply over –40 °C to +85 °C and is offered in a 48‑lead LFCSP package.
