Analog Devices AD9549 Handbook
The AD9549 is a dual‑input network clock generator and synchronizer that provides flexible reference inputs, loss‑of‑reference indicators, and automatic or manual holdover and switchover modes. It supports input frequencies from 8 kHz to 750 MHz and offers both HSTL and CMOS output drivers with programmable dividers and a digitally controlled oscillator core.
The document includes a full description of the device architecture, pin configuration, digital loop filter settings, holdover operation, and absolute maximum ratings. It also provides detailed DC and AC specifications, power consumption data, and guidelines for ESD protection and thermal performance.
