General Description:

The ACS401 is a complete optical-modem controller/driver/receiver IC, supporting various user programmable, fullduplex, synchronous data rates to 128 kbps over a single fiber. Communicating modems automatically maintain synchronisation with each other such that the receive phase of one modem is lined up with the transmit phase of the other, compensating for the propagation delay presented by the link.

ACS401 Main Features:

* Enables up to four full-duplex serial transmission channels through a single fiber optic cable, providing eight virtual fiber paths.

* Two additional low speed handshake signals.

* Supports Ping Pong LED (PPLED) and LASER Duplex Devices (LDD) for single fiber applications or dual fiber applications using low cost LED/LASER emitters and PIN Diode receiver.

* Link lengths up to 95 km with appropriate Laser.

* Maximum data rate 128 kbps - optimised for talk-set applications.

* Typical 7 mA (average) current consumption, including LASER drive current.

* Digital mode, allowing the user to add an external amplifier. Also enables the ACS401 to be used in non-fiber applications.

* Bit Error Rate (BER) of 10-9
