AD9516-1 is a 14-output clock generator with integrated 2.5 GHz VCO, the output clock frequency range is from 1.6 GHz to 800 MHz. This device has low phase noise, programmable delay, digital or analog lock detection and other features.
The AD9516-1 is a 14‑output clock generator IC that integrates a PLL and a VCO tunable from 2.30 GHz to 2.65 GHz. It can also accept an external VCO/VCXO up to 2.4 GHz. The device is intended for low‑jitter, low‑phase‑noise clock distribution in high‑speed data converters, wireless transceivers, instrumentation, and broadband infrastructure.
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), programmable delay and division, additive output jitter as low as 225 fs rms, and a 64‑lead LFCSP package powered from a single 3.3 V supply. The datasheet provides detailed specifications, pin descriptions, timing diagrams, and serial control port information.
