MT88E46AS Product Details
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 4wire 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.
· Compatible with Bellcore GR-30-CORE, SR-TSV-002476; TIA/EIA-716 and TIA/EIA-777
· Pin compatible with MT88E45
· Differential input amplifiers with adjustablegains for Tip/Ring and 4-wire side connections
· TIA(Telecommunications Industry Association)
MEI(Multiple Extension Interworking)
compatible architecture: CAS(CPE Alerting Signal) detection is selectable between Tip/
Ring and 4-wire side
·4-wire side CAS detection is Bellcore talkoff and talkdown compliant when near end speechis 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
·3to 5V±10% supply voltage· Uses 3.579545MHz crystal
. Low power CMOS with power down mode Applications
· Bellcore compliant CIDCW(Calling Identity Delivery on Call Waiting) and CWD(Call Waiting Deluxe) telephones
