HCPL-800J

www.DataSheet4U.com Agilent HCPL-800J PLC Powerline DAA IC Data Sheet Features -60 dB Overall Tx Distortion 25 nV/ Hz Typical Input Referred Noise Load Detection Function Description The HCPL- 800J is a galvanically isolated Powerline Data Access Arrangement IC. It provides the key features of isolation, Tx line driver and Rx amplifier as required in a powerline modem application. Used together with a simple LC coupling circuit, the HCPL- 800J offers a highly integrated, cost effective Analogue Front End (AFE) solution. Optical coupling technology provides very high isolation mode rejection, facilitating excellent EMI and EMC performance.
