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
