L8575 Datasheet (Agere Systems) - Low-Cost Subscriber Line Interface Circuit

L8575, Low-Cost Subscriber Line Interface Circuit

The L8575 is a dual-resistive, low-cost subscriber line interface circuit (SLIC) that is optimized to meet both ITU-T recommendations and LSSGR requirements for 600 Ω/900 Ω resistive and complex impedance termination applications.

It interfaces the lowvoltage circuits on an analog line card to the T
