XE0042V

The XE0042V provides four FCC compliant telephone interfaces in a compact package.The total package fills only 3.8 square.The total package fills only 3.8 square inches of board space.Each indentical telephone interface includes ring detection,off-hook control,and a 2 to 4 wire converter to isolate transmit and receve signals.The XE0042V satisfies the needs of voice grade applications and data applications up to and including V.32bis modems.

The XE0042V has some electrical specification.When parameter is power supply current,the conditions is Vcc,the TYP is 20,the MAX is 30,the units is mA.When parameter is transmission gain,the conditions is gain transmit input to telephone line at 1800 Hz,the MIN is -0.5,the TYP is 0,the MAX is +0.5,the units is dB.When parameter is phone line impedance,the conditions is at 1800 Hz,the MIN is 540,the TYP is 600,the MAX is 660,the units is Ohms.When parameter is transhybird loss,the conditions is attenuation between transmitter input and receiver output at 1kHz,the MIN is 12,the TYP is 18,the units is dB.When parameter is attenuation,the conditions is receive/transmit attenuation at 300 Hz with 600 ohm termination,the TYP is 0.8,the MAX is 3,the units is dB.When parameter is loop current switch control voltage,the conditions is ON:(off-hook),the MIN is 4.0,the units is Volts.When parameter is loop current switch control voltage,the conditions is OFF:(on-hook),the MAX is 0.8,the units is Volts.When parameter is loop current switch control current,the MIN is 1,the MAX is 4.0,the units is mA.When parameter is loop current ,the conditions is off-hook current draw from the telephone line,the MIN is 0,the TYP is 20,the MAX is 100,the units is ma.
