CPC5604

CP Clare's LITELINK™ family of single package DAA solutions can be used for a variety of telephone line interface applications including high performance 56kbps modems. The LITELINK™ family of products are advanced integrated circuits that use optical signal coupling techniques to provide the required electrical isolation between the telephone line and the user's host circuitry. The LITELINK™ family differs from other DAA solutions utilizing either optical or capacitive isolation techniques by including the barrier inside the IC package which eliminates the need for external high voltage capacitors or optocouplers in the data path, thus saving board space and lowering cost. The LITELINK™ family of products has been designed to meet or exceed the requirements of international regulatory agencies.

The CPC5600 was the first in the series of LITELINK™ products. The CPC5600 low profile package and optical isolation barrier offers designers the opportunity to implement a full DAA circuit using less board space than previously possible.

The CPC5604 is the next generation of LITELINK™ product. The CPC5604 offers the same optical isolation barrier and all the benefits of the CPC5600 along with a lower noise floor that allows higher data through put rates. The CPC5604 also takes the CP Clare's international solution one step further by simplifying the implementation of CTR21.

The key features of the LITELINK™ family of DAAs are as follows:
 ` Full differential or single ended transmit and receive signal coupling from the telephone line to the host system
 ` High voltage (1500 VRMS ) isolation between telephone line and host
 ` Ring signal detection
 ` Caller ID signal detection
 ` Hookswitch function
 ` Internal 2-4 wire converter
 ` Low power consumption
 ` Flat frequency response 30-4000Hz
 ` Low THD 80db
 ` Minimum number of external components required
 ` Programmable International solution with CPC5601 chip
 ` PC Card and PCMCIA compatible packaging
 ` Current Limiting

For international PTT compliance, external passive components can be changed to meet different country requirements. Using the LITELINK ™ in conjunction with the CPC5601 programmable driver, will offer a software programmable solution using a digital serial interface to the host's microcontroller. See CPC5601 Data Sheet for details on software programmable solutions.
