ACS103 Datasheet - Semtech Corporation

General Description:
The ACS103 is a complete synchronous optical modem controller/driver IC, supporting various user-programmable, full-duplex data-rates to 256 kbps over a single fiber. Alternatively, up to 3 channels of 64 kbps each can be carried. In 'Standard' mode, the fiber may be up to 2.5 km long, or up to 5 km in 'Double' mode.

Main Features:
* Enables three full-duplex serial transmission channels through a single fiber optic cable, providing a virtual six fiber path.
* Link lengths up to 5 km.
* Uses a single Ping Pong LED (PPLED) to both transmit and receive data.
* Supports 7 synchronous data rates up to 64 kbps or asynchronous data rates from DC to 19.2/9.6 kbps.
* Supports three additional low frequency asynchronous channels or RS-232 handshake signals: RTS, CTS, DTR and DSR.
* BER 10-9.
* Digital mode, allowing the user to add an external amplifier. Also enables the ACS103 be used in non-fiber applications e.g. IR/RF.
* ACS101 emulation mode giving 100 % compatibility with the ACS101.
