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.

Features

• Superior voice solution with low noise and excellent part-to-part gain accuracy

• 3 kVRMS 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:
