Product Summary
The FX614D4 is a low power CMOS integrated circuit for the reception or transmission of asynchronous 1200bits/sec data and is suitable for use in Bell 202 type systems. It is also capable of generating the 5bits/sec or 150bits/sec ‘back channel’. The FX614D4 incorporates an optional Tx and Rx data retiming function that removes the need for a UART in the associated mC when operating at 1200bits/sec. An optional line equaliser is incorporated into the receive path, this is controlled by an external logic level. The FX614D4 may be used in a wide range of telephone telemetry systems.
Parametrics
