The CMX654 is a low power integrated circuit, designed for the transmission of asynchronous 1200bits/sec data in accordance with ITU, V.23 and ETSI specifications. The device incorporates an optional Tx data retiming function. This device may be operated so that only the mark or space tone is produced. The CMX654 may be used in a wide range of telephone telemetry systems. With a low voltage requirement of 3.0V it is suitable for both portable terminal and line powered applications. A very low current 'sleep' mode (1PA typ.) and an operating current of 1mA typ. makes the CMX654 ideal for line powered applications. This device requires a standard 3.58MHz Xtal/Clock rate and operates from a 3.0 to 5.5V supply. Available packages are: 16-pin SOIC (CMX654D4) and 16-pin PDIP (CMX654P3). Additional package styles may be available to meet specific design requirements.
