Zilog Interface - Interface - Telecom - CPC5611A CPC5611A

The CPC5611A is a silicon data access arrangement (DAA) integrated circuit designed for full-duplex data and voice transmission. It features a transformerless telephone line isolation interface, making it suitable for applications requiring modem speeds up to V.90 (56K). The device operates with a power supply of either 3.3V or 5V and includes a full-wave ring detector, enhancing its performance in detecting ring signals. This IC is packaged in a compact 32-pin SOIC format, which helps save printed circuit board space and costs. It is compatible with worldwide dial-up telephone networks and can easily interface with modem ICs and voice CODECs. The CPC5611A meets various regulatory standards, including TIA/EIA/IS-968 and FCC part 68, ensuring compliance for telecommunication applications. Applications for the CPC5611A include satellite and cable set-top boxes, V.90 modems, fax machines, voicemail systems, and telephony gateways, among others. Its design eliminates the need for bulky isolation transformers, providing a more efficient solution for embedded modem applications.
