Overview
The AD9553BCPZ from Analog Devices Inc. is a phase-locked loop (PLL) based clock translator designed to address the needs of passive optical networks (PON) and base stations. This device employs an integer-N PLL to accommodate a wide range of frequency translation requirements. It offers flexibility in input options, supporting up to two single-ended input reference signals or one differential input reference signal via the REFA and REFB inputs. The AD9553 also supports holdover applications by allowing the connection of a 25 MHz crystal resonator to the XTAL input, ensuring uninterrupted performance even in the absence of the primary reference signal.
