The ISL5585EVAL4 evaluation board provides a complete PCM to 2W ringing SLIC/CODEC line card for the evaluation of the RSLIC18 family of 5V and 3.3V ringing SLICs (RSLIC). The evaluation board is designed to accommodate both the HC55185 5V and the ISL5585 3.3V and includes companion 5V and 3.3V CODECs from Winbond.
The 3.3V family of ringing subscriber line interface circuits (SLIC) supports analog plain old telephone service (POTS) in short and medium loop length, wireless and wireline voice over broadband applications. Ideally suited for customer premise equipment, this family of products offers flexibility to designers with high ringing voltage and low power consumption system requirements.
