AD9548BCPZ Durable Electronic IC Chip 725MHz For Data Communications

AD9548BCPZ Quad and Octal Input Network Clock Generator or Synchronizer IC

The AD9548 provides synchronization for many systems, including synchronous optical networks (SONET/SDH). The AD9548 generates an output clock synchronized to one of up to four differential or eight single-ended external input references. The digital PLL allows for reduction of input time jitter or phase noise associated with the external references. The AD9548 continuously generates a clean (low jitter), valid output clock even when all references have failed by means of a digitally controlled loop and holdover circuitry. The AD9548 operates over an industrial temperature range of −40°C to +85°C
