Modem (modulator-demodulator)
CML Microcircuits
The device incorporates an optional Tx and Rx data retiming function that removes the need for a UART in the associated C when operating at 1200bits/ sec. The device can disable the back channel or be operated so only the mark or space tone is produced. An optional line equaliser is incorporated into the receive path, this is controlled by an external logic level.
