LITELINK? III Phone Line Interface IC (DAA)


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.

• Superior voice solution with low noise, excellent part-to-part gain accuracy
• 3 kVrmsline 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, N55022B,
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
