AD9517-1 is a 12-output clock generator with integrated 2.5 GHz VCO. It features low phase noise, phase-locked loop, and various input/output options, making it suitable for a wide range of applications.
The AD9517-1 provides a multi‑output clock distribution function with sub‑picosecond jitter performance, an on‑chip PLL and VCO, and optional external VCO/VCXO support. It offers four LVPECL outputs, four LVDS outputs, and eight CMOS outputs, each with programmable division and coarse delay.
The device operates from a single 3.3 V supply, supports reference inputs up to 250 MHz, and is specified for industrial temperature range –40 °C to +85 °C. Detailed specifications, pin configurations, and timing characteristics are provided for system designers.
