Data

The 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.

The MX604 may be used in a wide range of telephone telemetry systems. Low voltage capability, a low

operating current (1mA typ. @ VDD = 3.3V), and a very low current 'sleep' mode (1A typ.) make the MX604

ideal for both portable terminal and line powered applications.

The MX604 is available in the following packages: 24-pin TSSOP (MX604TN), 16-pin SOIC (MX604DW) and

16-pin PDIP (MX604P).
