This document describes the AD9516-1 Rev. B model, a 14-output clock generator with an integrated 2.5 GHz VCO. It features a low phase noise PLL, supports multiple reference inputs, has automatic switchover and holdover modes, and provides multiple LVPECL and LVDS clock outputs.
The AD9516-1 provides multi‑output clock distribution with sub‑picosecond jitter, an on‑chip PLL and VCO that tunes from 2.30 GHz to 2.65 GHz. It supports differential LVPECL (up to 1.6 GHz), LVDS (up to 800 MHz) and single‑ended CMOS (up to 250 MHz) outputs, each with programmable division and fine delay.
The device operates from a single 3.3 V supply, with an optional external VCO/VCXO requiring a 5 V charge‑pump supply. It is specified for industrial temperature range –40 °C to +85 °C and includes serial control port, lock‑detect, and various power‑down modes.
