描述 Description

v.23 Compatible ModemThe MX604 is a low voltage, low power CMOS device, used for the reception or transmission of asynchronous
1200bps data and full-duplex 75bps back channel data in accordance with CCITT V.23 and ETSI
specifications.
This device provides an optional Tx and Rx data retiming function which can eliminate, based on user preference, the need for an external UART when operating at 1200bps. The device can disable the back channel or be operated so only the mark or space tone is produced. The optional line equalizer is incorporated into the receive path and is controlled by an external logic level.FEATURES
