AD9557BCPZ-REEL7 Description

Short technical summary and product information.

The AD9557BCPZ-REEL7 is a dual input multiservice line card adaptive clock translator from Analog Devices. It integrates a digital PLL with programmable loop filter and supports a wide range of input and output logic standards including CMOS, LVDS, LVPECL for inputs and CMOS, HSTL, LVDS for outputs. The device is designed for Ethernet, SONET/SDH clock synchronization applications.

 

Key specifications include a maximum frequency of 1.25 GHz, supply voltage range of 1.71V to 3.465V, and an operating temperature range of -40°C to 85°C. It features two reference inputs (single-ended or differential) and two pairs of configurable clock outputs. The device supports GR-1244 Stratum 3 holdover, smooth reference switchover, and meets Telcordia GR-253 and ITU-T G.8262 standards.

 

The AD9557BCPZ-REEL7 is supplied in a surface-mount 40-VFQFN Exposed Pad, CSP package with a supplier device package of 40-LFCSP-VQ (6x6). It is intended for use in line cards, base stations, and other network timing equipment requiring precise clock translation.
