MT8841AS

The MT8841AS is designed as one kind of calling number identification circuit (CNIC) that can be used in (1)calling number delivery (CND), calling name delivery (CNAM) and calling identity on call waiting (CIDCW) features of bellcore CLASSSM service; (2)feature phones; (3)phone set adjunct boxes; (4)fax machines; (5)telephone answering machines; (6)database query systems applications. This device providing an interface to various calling line information delivery services and accepts and demodulates both CCITT V.23 and BELL 202 signals.

Features of the MT8841AS are:(1)1200 baud BELL 202 and CCITT V.23 Frequency Shift Keying (FSK) demodulation; (2)Compatible with Bellcore TR-NWT-000030 and SR-TSV-002476; (3)High input sensitivity: -36dBm; (4)Simple serial 3-wire data interface eliminating the need for a UART; (5)Power down mode; (6)Internal gain adjustable amplifier; (7)Carrier detect status output; (8)Uses 3.579545 MHz crystal or ceramic resonator; (9)Single 5V power supply; (10)Low power CMOS technology.

The absolute maximum ratings of the MT8841AS can be summarized as:(1)DC Power Supply Voltage VDD to VSS: -0.3 to 6 V;(2)Voltage on any pin: -0.3 to VDD+0.3 V;(3)Current at any pin (except VDD and VSS): ±10 mA;(4)Storage Temperature: -65 to +150 °C;(5)Package Power Dissipation: 500 mW.

The electrical characteristics of this MT8841AS can be summarized as:(1)Standby Supply Current: 15 to 100 A;(2)Operating Supply Current: 3 to 5 mA;(3)Power Consumption: 28 mW;(4)Low Level Output Voltage: 0.4 V;(5)High Level Output Voltage: VDD-0.4 V;(6)Sink Current: 2.5 mA;(7)Input Current: 10 A;(8)Output Voltage: 2.45 to 2.55 V;(9)Output Resistance: 2 k.
