1 / 18 page  DS-CPC5622 - R02 www.clare.com 1 Features • Superior voice solution with low noise and excellent part-to-part gain accuracy • 3 kV RMS line isolation • Simultaneous ringing detection and CID monitoring for worldwide applications • Provides both full-wave ringing detect and half-wave ringing detect for maximum versatility • Transmit power of up to +10 dBm into 600 Ω • Data access arrangement (DAA) solution for modem speeds up to V.92 • 3.3V or 5 V power supply operation • Easy interface with modem ICs and voice CODECs • Worldwide dial-up telephone network compatibility • CPC5622 can be used in circuits that comply with the requirements of TIA/EIA/IS-968 (FCC part 68), UL60950 (UL1950), EN/IEC 60950-1 Supplementary Isolation Compliant, IEC60950, EN55022B, CISPR22B, EN55024, and TBR-21 • Line-side circuit powered from telephone line • Compared to other silicon DAA solutions, LITELINK: - Uses fewer passive components - Takes up less printed-circuit board space - Uses less telephone line power - Is a single-IC solution Applications • Computer telephony and gateways, such as VoIP • PBXs • Satellite and cable set-top boxes • V.92 (and other standard) modems • Fax machines • Voicemail systems • Embedded modems for POS terminals, automated banking, remote metering, vending machines, security, and surveillance Description LITELINK III is a single-package silicon phone line interface (PLI) DAA used in voice and data communication applications to make connections between low-voltage equipment and high-voltage telephone networks. LITELINK uses on-chip optical components and a few inexpensive external components to form the required high voltage isolation barrier. LITELINK eliminates the need for large isolation transformers or capacitors used in other phone line interface configurations. LITELINK also provides AC and DC phone line terminations, switchhook, 2-wire to 4-wire hybrid, ringing detection, and full time receive on-hook transmission capability. The CPC5622 is a member of and builds upon Clare’s third generation of LITELINK products with improved insertion loss performance and lower minimum current draw from the phone line. The CPC5622 version of LITELINK III provides concurrent ringing detection and CID monitoring for world wide applications. Both half-wave and full-wave ringing detection are provided for maximum versatility. Ordering Information Figure 1.
