Description
The MT88E45B is a low power CMOS integrated
circuit suitable for receiving the physical layer
signals used in North American (Bellcore) Calling
Identity Delivery on Call Waiting (CIDCW) and
Calling Identity Delivery (CID) services. It is also
suitable for ETSI and BT Calling Line Identity
Presentation (CLIP) and CLIP with Call Waiting
services.
The MT88E45B contains a 1200 baud Bell 202/
CCITT V.23 FSK demodulator and a CAS/DT-AS
detector. Two input op-amps allow the MT88E45B to
be connected to both Tip/Ring and the telephone
hybrid or speech IC receive pair for optimal CIDCW
telephone
architectural
demodulation is always on Tip/Ring, while CAS
detection can be on Tip/Ring or Hybrid Receive. Tip/
Ring CAS detection is required for the Bellcore/TIA
Multiple Extension Interworking (MEI) and BT’s on-
hook CLIP. A selectable FSK data interface allows
the data to be processed as a bit stream or extracted
from a 1 byte on chip buffer. Power management has
been incorporated to power down the FSK or CAS
section when not required. Full chip power down is
also available. The MT88E45B is suitable for
applications using a fixed power source (with a +/-
10% variation) between 3 and 5V.
