1 / 17 page  DS-CPC5620/CPC5621 - R04 www.clare.com 1 3kVrms Isolation RoHS 2002/95/EC e3 Pb Features • Superior voice solution with low noise, excellent part-to-part gain accuracy • 3 kV rms line isolation • Transmit power of up to +10 dBm into 600 Ω • Data access arrangement (DAA) solution for modems at speeds up to V.92 • 3.3 or 5 V power supply operation • Caller ID signal reception function • Easy interface with modem ICs and voice CODECs • Worldwide dial-up telephone network compatibility • CPC5620 and CPC5621 can be used in circuits that comply with the requirements of TIA/EIA/IS-968 (FCC part 68), UL1950, UL60950, EN/IEC 60950-1 Supplementary Isolation compliant, 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 - Offers simplified operation - 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 provides a high-voltage isolation barrier, AC and DC phone line terminations, switch hook, 2-wire to 4-wire hybrid, ring detection, and on-hook signal detection. LITELINK can be used in both differential and single-ended signal applications. LITELINK uses on-chip optical components and a few inexpensive external components to form a complete voice or high-speed data phone line interface. LITELINK eliminates the need for large isolation transformers or capacitors used in other interface configurations. It includes the required high-voltage isolation barrier in a surface-mount SOIC package. The CPC5620 (half-wave ringing detect) and CPC5621 (full-wave ringing detect) build upon Clare’s LITELINK product line, with improved insertion loss control, improved noise performance, and lower minimum current draw from the phone line. The new mode pin enables worldwide implementation. Ordering Information Figure 1.
