CPC5710 Phone Line Monitor IC
Clare’s CPC5710N 8-pin SOIC is a versatile building block for
designing telephone line monitoring circuits. High common-
mode rejection ratio (>40dB) and high input impedance makes
the CPC5710N an excellent choice for tip/ring voltage
monitoring, battery presence detection, line-in-use detection
(another-phone-off-hook), polarity reversal, display feature
(Caller ID) signal reception, ringing detection, and discrete
voice recording.
The CPC5710N high impedance input circuit eliminates phone
line monitoring discrete components that reduce central office
Features
• Excellent common-mode rejection ratio (CMRR), >40 dB
• Supplied application circuits meet EN60950 Safety and
• High input impedance circuit eliminates line voltage drop
• Small 8-pin SOIC
• Worldwide telephone network compatibility
• Full-wave ringing level detector comparator with internal
• 3.3V to 5V operation
• High differential input impedance, very low common mode
• Fixed gain
• Differential or single-ended linear output
• TTL logic input
• CMOS logic output (TTL compatible)
• Virtually non-detectable in voice monitoring

(CO) battery voltage to Customer Premise Equipment (CPE)
equipment. This allows the CPE equipment to work properly on
long phone loops and meet difficult worldwide regulatory low
CO voltage conditions. The high impedance resistive barrier
application circuit is fully compliant to the EN60950 safety
standard and meets the ITU-T K.21 over-voltage and over-
current specifications. Common applications include telephony
gateways, IP-PBX, computer telephony, embedded modems,
set-top boxes, voice recording applications, and point-of-sale
equipment.
Applications
In monitoring applications the 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 polarity
