3.58MHz Xtal/Clock Rate
1.1
Brief Description
The FX614 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 device incorporates an optional Tx and Rx data retiming function that removes the need for a UART in the
associated
碌
C when operating at 1200bits/sec. An optional line equaliser is incorporated into the receive path,
this is controlled by an external logic level.
The FX614 may be used in a wide range of telephone telemetry systems. With a low operating voltage of
3.0V, a very low current 'sleep' mode (1
碌
A) and an operating current of 1mA the device is ideal for portable,
terminal and line powered applications. A 3.58MHz standard Xtal/Clock rate is required and the device
operates from a 3.0V to 5.5V supply. Both SOIC (D4) and Plastic DIL (P3) 16-pin package types are available.
