AMC2442 CV AMC2442CV APPLICATIONS The AMC2442 Serial Modem Controller is designed to act as a fully stand alone modem controller device. To build a complete functional modem simply requires the addition of a modem front end circuit. The AMC2442 supports the 73K321, 73K222, 73K224, and 73K324 devices manufactured and supplied by TDK Semiconductor Corp. (USA) in both their AL and BL version where available. Full autobauding is supported on the DTE interface at data speeds of 300, 600, 1200, 2400, 4800, and 9600 bps (19200 TBA), and the device runs from either an external clock BLOCK DIAGRAM CLKo source or a single crystal running at 11.0592MHz. This makes the AMC2442 the perfect companion part to TDK devices, which use the same clock frequency. The simplicity of the resulting modem design makes the AMC2442 ideal for use in applications where the modem is a secondary function, and whe...
