Line Card Access Switch

Features

Description

• Improved switch dV/dt immunity of 1500 V/μs

• Drop-In Replacement for CPC7591

• Replaces CPC7581, and allows removal of

power-up control discrete components

• TTL logic level inputs for 3.3V logic interfaces

• Smart logic for power up / hot plug state control

• Small 16-pin SOIC package

The CPC7691 is a member of Clare’s third-generation

Line Card Access Switch (LCAS) family. This

monolithic 4-pole solid state switch is available in a

16-pin SOIC package. It provides the necessary

functions to replace the 2-Form-C electromechanical

ringing relay and it’s associated snubber circuitry on

traditional analog line cards or contemporary

• Monolithic IC reliability

integrated voice and data (IVD) line cards found in

Central Office (CO), Access, and PBX equipment.

Because this device contains solid state switches for

tip and ring line break and for ringing injection/return, it

requires only a +5 V supply for operation and TTL

logic-level inputs for control. The CPC7691 provides

stable start-up conditioning during system power up

and for hot plug insertion applications. Once active,

the inputs respond to traditional TTL logic levels,

enabling the CPC7691 to be used with 3.3V-only logic.

• Low, matched R

• Eliminates the need for zero-cross switching

• Flexible switch timing for transition from ringing

mode to idle/talk mode.

• Clean, bounce-free switching

• Tertiary protection consisting of integrated current

limiting, voltage clamping, and thermal shutdown for

SLIC protection

• 5 V operation with power consumption < 10.5 mW

• Intelligent battery monitor

For negative transient voltage protection the

CPC7691BA version includes SCRs to provide

voltage fold-back protection for the SLIC and

subsequent circuitry, while the CPC7691BB version

• Latched logic-level inputs, no external drive circuitry

Applications

• VoIP Gateways

• Central office (CO)

• Digital Loop Carrier (DLC)

• PBX Systems

utilizes clamping diodes to the V

pin. For positive

BAT

transient voltage protection all versions provide

clamping diodes to the F

pin.

GND

• Digitally Added Main Line (DAML)

• Hybrid Fiber Coax (HFC)

• Fiber in the Loop (FITL)

• Pair Gain System
