Product Summary

The MX614TN is a low voltage, low power CMOS integrated circuit designed for the reception or transmission of asynchronous 1200bps data. The MX614TN is compatible with Bell 202 type systems. The mx614tn supports 5bps and 150bps back channel operation. The MX614TN provides an optional Tx and Rx data retiming function which can eliminate, based on user preference, the need for a UART in the associated μC when operating at 1200bps. An optional line equalizer has been incorporated into the receive path and is controlled by an external logic level. Applications of the MX614TN include: Low voltage operation (3.3V to 5.0V); Low power operation: 1mA typ. @ 3.3V operating mode, 1μA typ. Zero-power mode; Standard 3.58MHz xtal/clock; Telephone telemetry applications.
