1.1 Brief Description
The CMX654 is a low power CMOS integrated circuit 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. The device can 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 (1µA
typ.) and operating current of 1mA typ. mean the device is ideal for line powered applications. A 3.58MHz
standard Xtal/Clock rate is required and the device operates from a 3.0 to 5.5V supply. Both SOIC (D4) and
Plastic DIL (P3) 16-pin package types are available.
