DESCRIPTION
The SC88E43 Calling Number Identification Circuit 2(ECNIC2) is a low power CMOS integrated circuit intended for receiving physical layer signals transmitted according to BT (British Telecom) SIN227 & SIN242, the U.K.’s CCA (Cable Communications Association) TW/P&E/312 and Bellcore GR-30-CORE & SR-TSV-002476 specifications. The SC88E43 is suitable for applications using a fixed voltage power source between 3 and 5V ±10%.

FEATURES
* Compatible with:
    -- British Telecom (BT) SIN227 & SIN242
    -- U.K.’s Cable Communications Association (CCA) specification TW/P&E/312
    -- Bellcore GR-30-CORE (formerly known as TR-NWT-000030) & SR-TSV-002476
* Bellcore “CPE” Alerting Signal” (CAS) and BT “Idle State Tone Alert Signal” detection
* Ring and line reversal detection
* 1200 baud Bell 202 and CCITT V.23 Frequency Shift Keying (FSK) demodulation
* 3 or 5V ±10% supply voltage
* High input sensitivity (-40dBv Tone and FSK Detection)
* Selectable 3-wire FSK data interface (microcontroller or SC88E43 controlled)
* Low power CMOS with powerdown mode
* Input gain adjustable amplifier
* Carrier detect status output
* Uses 3.58 MHz crystal

APPLICATIONS
* BT Calling Line Identity Presentation (CLIP), CCA CLIP, and Bellcore Calling Identity Delivery (CID) systems
* Feature phones, including Analog Display Services Interface (ADSI) phones
* Phone set adjunct boxes
* FAX and answering machines
* Database query and Computer Telephony Integration (CTI) systems
