Clare Introduces the LITELINK III IC with New Caller ID and Ringing Detect Features for the VoIP Gateway Market.

BEVERLY, Mass. -- IXYS (Nasdaq:SYXI) announced that its Clare division introduced the newest member of the LITELINK(TM) III Phone Line Interface IC family, the CPC5622A, for direct access arrangements (DAAs) in telephony applications. LITELINK(TM) products are used extensively in foreign exchange office (FXO) ports for IP-PBXs and voice over internet protocol (VoIP) gateways as well as modem equipment. The latest LITELINK(TM) III device features simultaneous phone line ringing detect and caller-ID (CID) monitoring which greatly simplifies DAA designs particularly for international telephony applications. In addition, the CPC5622A offers both half-wave and full-wave ringing detect outputs to support most codec and DSP devices.

Telephony systems in specific countries around the world need to detect CID information before a ringing signal is transmitted which in the past required additional discrete components. Internal CID and ringing detect circuitry on the CPC5622A eliminates the need for these components providing an immediate cost saving per telephone line.

"The CPC5622A offers the best set of DAA features for meeting the demands of the high growth, international telephony FXO market," said Steve Andrezyk, Director of Marketing for Clare. "The additional control features to handle country specific CID and ringing requirements helps OEMs reduce costs and board space real estate which is particularly important in multi-channel designs."

LITELINK(TM), which is the world's only single IC package DAA, has been used in numerous products from embedded modem applications to internet telephony gateways and FXOs. The internal optical barrier of the device separating the phone-line side from the host-side has provided end-users with a low noise, low distortion DAA that meets international regulatory requirements. The increased 3000Vrms isolation barrier further enhances the surge robustness of LITELINK(TM)-based OEM equipment.

Clare's LITELINK(TM) III offers a broad feature set including high-voltage isolation, proper AC and DC phone line terminations, 2-to-4 wire hybrid function, on-hook and off-hook detection, caller ID and ring detect circuitry.
