Clare Launches CPC5710 Telecommunications IC

Clare Inc. (Beverly, MA) announced the first in a new category of telecommunication ICs, the CPC5710N phone line monitor (PLM), which can be used by itself for phone line monitoring applications, or it can be used in conjunction with the Clare LITELINK phone line interface IC/DAA (CPC5621A) for a complete voice or data phone line interface solution with line condition sensing.

The CPC5710N IC implements telephone line interface functions, previously available only with discrete components, saving printed-circuit board space and cost. The CPC5710N is a CMOS special-purpose amplifier with an additional comparator circuit. The common-mode rejection ratio of over 40dB makes the CPC5710N suitable for telephone line condition sensing, discrete voice recording and signal monitoring applications.

The CPC5710N is packaged in a small eight-pin SOIC package, with TTL compatible inputs and CMOS logic outputs. The CPC5710N operates on either a 3.3V or a 5V power supply.
