Description
The ACS102A is a complete controller, driver and receiver IC, supporting full duplex asynchronous transmission from DC to 162kbps over a single serial link. Although primarily designed for single optical fibre applications, any other simple serial media may be used. The ACS102A is optimised for very low power consumption, consuming only 2 - 3mA at RS-232 data rates including power provided to the LED and 'heartbeat' monitor. In applications where the power is extracted from the RS232 data lines, this leaves a generous amount of power left for any power extraction and RS-232 level shifting circuitry.

FEATUREs
* Full duplex serial transmission over single/twin fiber.
* Link lengths up to 25km.
* Supports asynchronous data rates from DC to 162kbps.
* Full diagnostic modes - Remote and Local loopback.
* Ultra low power consumption, typically 2-3mA, which could be extracted from the RS-232 port for self powered applications.
* Uses a single Ping Pong LED or Laser Duplex Device for single fiber applications, low cost LED/PIN or Laser/PIN combinations for twin fiber applications.
* Additional operating mode to support PIN with integrated TIA.
* Supports 3 additional low frequency asynchronous channels or the RS-232 handshake signals.
* Digital and differential voltage input modes, plus modes for non fiber applications - RF
* Bit Error Rate (BER) < 10^-9
* Available in 44 pin TQFP (part no: ACS102A-TQ) and 44 pin PLCC (part no: ACS102A-PL) packages.
