AD9554 Datasheet (Analog Devices) - Multiservice Line Card Adaptive Clock Translator

AD9554, Multiservice Line Card Adaptive Clock Translator

The AD9554 is a low loop bandwidth clock translator that provides jitter cleanup and synchronization for many systems, including synchronous optical networks (SONET/SDH).

The AD9554 generates an output clock synchronized to up to four external input references.

The digital PLL (DPLL) allows for redu
