April 17, 2008–Beverly, Massachusetts, USA – Clare, Inc., an IXYS company (NASDAQ: IXYS – News), announced the immediate availability of the CPC5712. This special purpose Phone Line Monitor with Detectors (PLMD) integrated circuit is used in various high-voltage telephony applications such as VoIP (Voice over Internet Protocol) gateways and IP-PBXs.

The CPC5712 monitors the TIP/RING input through a high-impedance divider (resistor isolation), and derives two programmable signal-level detects, polarity information, and the buffered phone line signal itself. The device offers improved detector accuracy and performance including lower power dissipation as well as a high degree of integration compared to earlier devices. The resistor divider and the 10Megohm input impedance of the CPC5712 make the circuit practically undetectable for both on- and off-hook phone line applications

Requiring minimal external components, the common-mode rejection ratio of over 55dB makes the CPC5712 excellent for telephone line condition sensing in high-noise environments. The CPC5712 application circuit meets the isolation requirements of worldwide telephony standards and provides international telephone network compatibility

The CPC5712 can be used by itself for phone line monitoring applications, or it can be used in conjunction with the Clare LITELINK (CPC5622) Phone Line Interface IC/DAA (Data Access Arrangement) for a complete voice or data phone line interface solution with line condition sensing.

"By leveraging Clare's core telephony competency and LITELINK silicon DAA technology, the CPC5712 delivers a superior solution to designers of telephone-network interfaces," said Mark Heisig, General Manager and Vice-President of Clare.

Pricing and Availability

CPC5712U is available in a small QSOP 16-lead package, in both sample and production quantities. For OEM quantities of 25,000 units, the CPC5712 is $0.49 with a standard lead-time of six weeks after receipt of order.
