AD9548 Rev. B is a Quad/Octal Input Network Clock Generator/Synchronizer from Analog Devices, supports Stratum 2 stability, reference switching and reference switching, supports 1Hz to 750MHz input reference frequency, and output frequency up to 450MHz
The AD9548 is a quad/octal input network clock generator/synchronizer that supports Stratum 2 stability, hit‑less reference switchover, and programmable input reference priority. It offers four pairs of reference inputs and four pairs of configurable clock outputs, with output frequencies up to 450 MHz and a 30‑bit programmable feedback divider.
Typical applications include network synchronization, jitter cleanup, GPS 1‑PPS synchronization, SONET/SDH clocks up to OC‑192, and wireless base‑station controllers. The device operates over an industrial temperature range of –40 °C to +85 °C and is supplied in an 88‑lead LFCSP package.
