AD9516-2 is a 14-channel clock generator from Analog Devices. It features an integrated 2.2 GHz VCO, low phase noise, high stability and high precision.
The AD9516-2 is a 14‑output clock generator with an integrated 2.2 GHz VCO, offering low phase‑noise and low jitter performance for high‑speed data converters, wireless transceivers, and instrumentation. It supports both internal and external VCO/VCXO options and provides programmable delays, reference monitoring, and automatic synchronization of all outputs on power‑up.
Key features include three pairs of LVPECL outputs (up to 2.95 GHz), two pairs of LVDS outputs (up to 800 MHz), eight CMOS outputs (up to 250 MHz), and a 64‑lead LFCSP package that operates from a single 3.3 V supply. The device operates over an industrial temperature range of –40 °C to +85 °C and offers extensive configuration via a serial control port.
