Low Power Cmos Intergrated Circuit

The Winbond Caller Identification device W91031 is a low power CMOS integrated circuit used to receive physical layer signals transmitted according to Bellcore and British Telecom (BT) specifications. There are two types of Caller Identifications, the first type is on-hook calling with caller ID message and the second type is call on waiting. The W91031 device provides all the features and functions of the Caller Identification specification for both these types, including FSK demodulation, Tone Alert Signal detection and ring detection. The FSK demodulation function CAN demodulate Bell 202 and CCITT V.23 Frequency Shift Keying (FSK) with 1200 baud rate. The Tone Alert Signal detect function CAN detect the dual Tones of the Bellcore CPE* Tone Alerting Signal (CAS) and the BT idle State and Loop State Tone Alert Signal. The line reversal for BT, ring burst for CCA or ring signal for Bellcore CAN be detected by the ring detector. By Winbond Electronics Corp America
