Line Card Access Switch

Features

Description

• TTL logic level inputs for 3.3V logic interfaces

• Smart logic for power up / hot plug state control

• Monolithic IC reliability

The CPC7508 is a member of Clare’s next generation

Line Card Access Switch family. When used with

ringing SLICs it provides the necessary functions to

replace the two 2-Form-C electromechanical test

relays used in contemporary Fiber To The Home

(FTTH) and Optical Network Unit (ONU) deployments

as well as Voice over IP (VoIP) telephony terminals.

• Low matched R

• Clean, bounce-free switching

• Tertiary protection consisting of integrated current

limiting and thermal shutdown for SLIC protection

• +12.5V operation with power consumption ≤25mW

• Latched logic level inputs, no external drive circuitry

required

Solid state switches provide the mechanism for tip and

ring line break, drop test, and channel test while

requiring only a single +12V supply for operation.

Interface compatibility with 3.3V or 5V logic for switch

state control is provided by the TTL logic level inputs.

• Small 16-pin SOIC

The CPC7508 is designed for fiber access units where

EMR’s are used for test access and line monitoring

functions but solid-state switches are desired due to

reduced operating noise, lower power consumption

and longer lifetimes.

Applications

• Fiber to the Home (FTTH)

• Fiber in the Loop (FITL)

• VoIP Gateways

• PBX Systems

• Digitally Added Main Line (DAML)

• Hybrid Fiber Coax (HFC)

This monolithic 8-pole solid-state switch is available in

a 16-pin SOIC package.
