Si3239x Analog Interface ProSLIC®

The Si32391 is a single channel analog interface SLIC solution and the Si32392 is a dual channel analog interface SLIC. The Si3239x SLICs are ideal for customer premise equipment, such as voice-over-IP-embedded multimedia terminal adaptors (EMTAs) and GPON or EPON optical network terminal (ONT) gateways. Each device’s ringing and dc feed voltages are designed to support short and medium loop lengths with a battery supply voltage rating of up to –136 V. Additionally, they enable key line-test functions for remote diagnostics.
