Description

•

4-wire side CAS detection is Bellcore talkoff

and talkdown compliant when near end speech

is attenuated 8dB or better, and is close to

talkoff compliant even without near end speech

attenuation

Tip/Ring side CAS detection typically meets

talkdown condition 1 (the average case)

1200 baud Bell 202 and CCITT V.23 FSK

demodulation

Selectable 3-wire FSK data interface (serial bit

stream or 1 byte buffer) with facility to monitor

stop bit for framing error check

FSK carrier detect status output

3 to 5V 10% supply voltage

Uses 3.579545MHz crystal

Low power CMOS with power down mode

The MT88E46 is a CMOS integrated circuit suitable

for receiving the FSK and CAS signals in North

American (Bellcore) CIDCW, CWD and CID (Calling

Identity Delivery) services. It provides an optimal

solution for the CIDCW (also known as Type 2) and

CWD (Type 2.5) telephone set applications by

providing separate input op-amps for Tip/Ring and 4-

wire side (receive pair of the telephone hybrid or

speech IC) connections. The Tip/Ring connection is

compatible with TIA’s MEI scheme and can be used

for FSK demodulation and ‘on hook mode’ CAS

detection. The 4-wire side connection is for ‘off hook

mode’ CAS detection. The CAS detection modes - on

hook and off hook - use different algorithms which

are optimized for the CPE states. In ‘off hook mode’

the CAS detector is Bellcore compliant when near

end speech is attenuated 8dB or better. ‘On hook

mode’ is optimized for talkdown only and typically

meets talkdown condition 1 (the average case)

without speech attenuation at Tip/Ring such as in the

on hook state MEI CPE.
