Description
The FX614 is a low power CMOS integrated circuit for the reception or transmission of asynchronous 1200bps data and is suitable for use in Bell 202 type systems. It is also capable of generating the 5bps or 150bps 'back channel'.
The device incorporates an optional Tx and Rx data retiming function that removes the need for a UART in the associated µC when operating at 1200bps. An optional line equaliser in incorporated into the receive path, this is controlled by an external logic level.
The FX614 may be used in a wide range of telephone systems. With a low operating voltage, a very low- current 'sleep' mode and an operating current of 1mA the device is ideal for portable, terminal and line powered applications. A 3.58MHz standard Xtal/Clock rate is required and the device operates from a 3.0V to 5.5V supply. Both SOIC (D4) and Plastic DIL (P3) 16-pin package types are available.
