Description

•

The MT88E45 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.

•

Separate differential input amplifiers with

adjustable gain for Tip/Ring and telephone hybrid

or speech IC connections

•

Selectable 3-wire FSK data interface (bit stream

or 1 byte buffer)

Facility to monitor the stop bit for framing error

check

FSK Carrier detect status output

3 to 5V +/- 10% supply voltage

The MT88E45 contains a 1200 baud Bell 202/CCITT

V.23 FSK demodulator and a CAS/DT-AS detector.

Two input op-amps allow the MT88E45 to be

connected to both Tip/Ring and the telephone hybrid

or speech IC receive pair for optimal CIDCW

•

Uses 3.579545MHz crystal or ceramic resonator

Low power CMOS with power down

telephone

architectural

implementation.

FSK

demodulation is always on Tip/Ring, while CAS

detection can be on Tip/Ring or Hybrid Receive. Tip/

Ring CAS detection is required for Bellcore’s

proposed 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 MT88E45 is

suitable for applications using a fixed power source

(with a +/-10% variation) between 3 and 5V.

Applications

•

Bellcore CID (Calling Identity Delivery) and

CIDCW (Calling Identity Delivery on Call

Waiting) telephones and adjuncts

ETSI, BT CLIP (Calling Line Identity

Presentation) and CLIP with Call Waiting
