CPC5710N

Phone Line Monitor (PLM) IC

Features

Description

• Excellent common-mode rejection ratio (CMRR),

>40 dB

• Supplied 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 CMOS special purpose

fixed-gain amplifier with comparator for telephone line

monitoring. The high (>40 dB) common-mode

rejection ratio makes the CPC5710N an excellent

choice for signal monitoring, discrete voice recording,

and line condition monitoring applications. The

CPC5710N is ideal for modem applications including

embedded modem designs like set-top boxes, and

voice recording applications.

• 3.3 or 5.0 Volt operation

• High differential input impedance, very low common-

mode input impedance

• Fixed gain

Ordering Information

• Differential or single-ended linear output

• TTL logic input

• CMOS logic output (TTL compatible)

• Virtually non-detectable in voice monitoring

applications

Applications

• In signal monitoring applications, CPC5710N can be

used for:

• Display feature (caller ID) signal processing

• Line-in-use detection (another-phone-off-hook)

• Ringing signal level detection

• Battery presence monitoring

• Tip and ring lead voltage monitoring

• Line condition detection, including line polarity, tip

and ring lead voltage, and battery presence
