MX919

The MX919 is designed as one kind of high-speed four-level FSK "packet data" modems which provides a versatile frame structure for general-purpose applications. The MX919 is designed specifically for the ARDIS RD-LAP network. With the help of a low power requirement of 5.0 mA at 5 volts, this device provides:(1)automatic handling of general purpose and RD-LAP frame structures;(2)4-level FSK baseband modulation enables high-speed, economical data rates in a narrow RF bandwidth;(3)on-chip baseband processing and filtering;(4)pre-selectable signal acquisition and tracking permits the rapid acquisition of received signals.

Features of the MX919 are:(1)MX-COM MX'D signal CMOS;(2)FM radio packet data applications;(3)4-level FSK-4.8/9.6/19.2 kbps;(4)low power requirement;(5)custom frame capabilities;(6)automatic protocol handling such as symbol and frame sync, block formatting, forward error correction and CRC check and generation;(7)PCMCIA packaging available.

The absolute maximum ratings of the MX919 can be summarized as:(1)supply voltage:-0.3 to 7.0 V;(2)input voltage at any pin:-0.3 to (VDD+0.3 V);(3)sink/source current (supply pins):+/-30 mA;(4)sink/source current (other pins):+/-20 mA;(5)total device dissipation:800 mW max.;(6)total device dissipation derating:10 mW/;(7)operating temperature:-40 to +85;(8)storage temperature:-55 to +125.
