Preliminary W91030B
The Winbond Caller Identification device W91030B, 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 W91030B 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.
There are two modes of FSK data output interface. The first mode is a data transfer activated by the
device, whose clock and data change depending upon the changing frequency of the FSK analog
signal input. The second mode allows a microcontroller to extract 8-bit data from the device serially;
the device notifies the micro-controller when 8-bit data has been received.
