Line Card Access Switch IC suits CPE telephony gateways.
July 2, 2009 -
Designed for Ringing SLICs (Subscriber Line Interface Circuit), CPC7508 monolithic high voltage IC features 8 digitally controlled MOSFET switching relays for bidirectional transmission. It replaces pair of 2-Form-C electromechanical relays and driver circuitry, while providing integrated current limit and thermal shutdown protection in each high-voltage switch. Available in 16-pin SOIC package, device offers 3.3 or 5 V logic for switch state control TTL logic level inputs.

Clare Introduces Industry's First LCAS IC for Ringing SLICs
New CPC7508 Line Card Access Switch (LCAS) IC Addresses Latest Customer Premises Equipment (CPE) Telephony Gateways such as Fiber-to-the-home, VoIP, DSL, Cable, and Others
June 11, 2009 - Beverly, Massachusetts, USA, Clare, Inc., an IXYS company (NASDAQ: IXYS - News) and world leader in the design and manufacture of high voltage, analog and mixed signal ICs, announces the immediate availability of the CPC7508 LCAS for Ringing SLICs (Subscriber Line Interface Circuit). This versatile monolithic high voltage IC features eight digitally controlled MOSFET switching relays for bidirectional transmission particularly for ringing SLIC (RSLIC) telephony applications. The device replaces a pair of 2-Form-C electromechanical relays (EMRs) and the requisite driver circuitry. In addition, surge protection costs for the ringing SLIC (RSLIC) are greatly reduced due to the integrated current limit and thermal shutdown protection in each high-voltage switch on the CPC7508. A substantial bill-of-material parts and cost savings is achieved as well as a significant reduction in board space.
The CPC7508 is used between the RSLIC and the telephony loop in applications such as Optical Network Units (ONU). Semiconductor MOSFET switches provide tip and ring line break, drop test and channel test functions while requiring only a single +12V supply for operation. The device replaces bulky EMRs that are currently used in test access and line monitoring functions. The CPC7508 also provides additional switches and integrates more functionality than restricted test capability RSLICs having a limited number of internal switches. Compatibility with 3.3V or 5V logic for switch state control is provided by the TTL logic level inputs.
The CPC7508 is made in Clare's bonded-wafer, silicon-on-insulator, 330V BCDMOS process with trench isolation, which has been used for many years in central office telecom equipment requiring long operational life (20+ years). The CPC7508BA is available in a 16-pin SOIC package, in both sample and production quantities.
Pricing and Availability
The CPC7508 Line Card Access Switch (LCAS) for Ringing SLICs is currently available in production quantities.
For OEM quantities of 10KU, pricing is $1.72, with a standard lead-time of eight weeks ARO.
