Overview
The AD9550BCPZ-REEL7 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, making it a versatile component for multiple communication standards.
It accepts a single-ended input reference signal and provides two independently programmable output clocks that can be configured as LVDS, LVPECL, or CMOS. The device is known for its low power consumption, small package size, and compliance with Telcordia GR-253-CORE jitter specifications.
