AD9512 is a 1.2 GHz clock distribution IC with 1.6 GHz inputs, dividers, delay adjustment and five outputs.
The AD9512 provides five independent clock outputs—three LVPECL at 1.2 GHz and two selectable LVDS (800 MHz) or CMOS (250 MHz) outputs. Each output includes a programmable integer divider (1‑32) and fine‑delay adjustment for precise timing.
Designed for low jitter and low phase‑noise applications, the device operates from a single 3.3 V supply and works over a temperature range of –40 °C to +85 °C. It is offered in a 48‑lead LFCSP package and includes a serial control port for configuration.
