DS26324: 16-port short-haul line interface unit

In Electronic Infomation Category: D | on April 26,2011

DS26324 support 3.3V power supply system, 16-port E1/T1/J1 short line interface unit (LIU). Through the internal impedance matching circuit supports a variety of applications, only a small number of external components to support E1/T1/J1 work. Using non-invasive monitoring, the best impedance mode and DS96172CN datasheet and 1:1 or 1 +1 redundant operation Enhanced backup support. Built-in frequency synthesizer from a master clock input to generate different frequencies E1/T1/J1 clock. The chip also provides two reference clock output, a 256-pin TEBGA package is the smallest 16-channel package LIU.
