CPC5710N

Phone Line Monitor (PLM) IC

Features

Description

• Excellent common-mode rejection ratio (CMRR)

• Application circuits can meet isolation requirements

of worldwide telephony standards

• Small 8-pin SOIC

• Worldwide telephone network compatibility

• Full-wave ringing level detector comparator with

internal threshold, large hysteresis, and logic-level

output

The Clare CPC5710N is a selectable dual function

CMOS special purpose integrated high-impedance

input, fixed-gain amplifier and an internally set voltage

level comparator for telephone line monitoring. The

high (>40dB) common-mode rejection ratio makes the

CPC5710N an excellent choice for signaling detection,

line condition monitoring, discrete voice recording and

CID buffering applications. In addition to voice

applications, the CPC5710N is ideal for data

• 3.3V or 5V operation

• High differential input impedance

• Very low common-mode input impedance

• Fixed gain

applications such as embedded modem designs

utilized in broadband set-top boxes.

• Differential or single-ended linear output

• TTL logic level input

• CMOS logic level output (TTL compatible)

• Virtually non-detectable in voice monitoring

applications

Applications

• The CPC5710N can be used for line monitoring or

detection of signaling states and loop conditions

such as:

• Display feature (caller ID) signal buffering

• Line-In-Use (LIU) detection

• Ringing signal with adjustable detection level

• Battery presence monitoring

• Tip to ring line voltage monitoring

• Line polarity

• Imperceptible voice recording
