Phone Line Monitor with Detectors (PLMD)

Features

Description

• CPC5712 Outputs:

• Two Independent Programmable Level Detectors

with Programmable Hysteresis

• Fixed-Level Polarity Detector with Hysteresis

• Differential Linear Output

The CPC5712 is a special purpose Phone Line

Monitor with Detectors (PLMD) integrated circuit that

is used in various high-voltage telephony applications

such as VoIP gateways and IP-PBXs. The device

monitors the TIP/RING potential through a

• Minimum External Components

• Excellent Common-Mode Rejection Ratio

(CMRR) > 55dB

• Application circuits meet isolation requirements of

worldwide telephony standards

• Worldwide telephone network compatibility

• Single Supply Operation, 3.0V to 5.5V

• High differential input impedance

• Very low common-mode input impedance

• Fixed Gain

high-impedance divider (resistor isolation) to derive

two programmable signal level detects, polarity

information, and a scaled representation of the phone

line voltages. In use, the resistor divider and the high

input impedance of the CPC5712 make the circuit

practically undetectable on the line.

The two voltage-level detects are programmed with

external resistors, which gives the designer complete

freedom with respect to line voltage detection levels.

The level settings also have programmable hysteresis

to prevent false triggering conditions. Detection of

these levels allows the user to determine the condition

of the line.

• TTL Compatible CMOS Logic Level outputs

• Small SOP 16-Lead package

Applications

• VoIP Gateways, IP-PBX, xDSL

• TIP/RING Monitoring

• Line-In-Use Detection

• Polarity Detection for Caller ID, Enhanced 911

• Battery Detection, PSTN Check

• Non-telephony voltage level detection applications

• Instrumentation

This device can also be used in non-telephony

applications such as instrumentation and industrial

controls, especially when a low-level differential level

needs to be detected in the presence of a large

common-mode voltage.
