CPC5621集成电路（IC）的电信规格书PDF中文资料

描述 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.

特性 Features

• 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
