Overview
The AD9550BCPZ is a phase-locked loop (PLL) based clock translator designed by Analog Devices Inc. to address the needs of wireline communication and base station applications. This device employs an integer-N PLL to accommodate various frequency translation requirements. It accepts a single-ended input reference signal and provides a matrix of standard input/output frequency translations. The AD9550BCPZ is implemented in a strictly CMOS process and operates over the extended industrial temperature range of −40°C to +85°C.
