CPC5710N

Phone Line Monitor (PLM) IC

INTEGRATED

IRCUITS

IVISION

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 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

applications such as embedded modem designs

utilized in broadband set-top boxes.

• 3.3V or 5V operation

• High differential input impedance

• Very low common-mode input impedance

• Fixed gain

• Differential or single-ended linear output

• TTL logic level input

• CMOS logic level output (TTL compatible)

• Virtually non-detectable in voice monitoring

applications
