Description
The ACS104A is a complete controller, driver and receiver IC, supporting full duplex asynchronous transmission from DC to 162kbps over a serial link. Improved sensitivity and additional operating modes are offered over the
ACS104. Although primarily designed to be used with standard LED emitters and PIN receivers and twin optical fibers, any other simple serial media may be used.

FEATUREs
* Low cost, single-chip solution for data powered RS-232 modems
  using twin fiber-optic cables. Includes all analog/digital functions
  except for power extraction circuitry and RS-232 level shifting.
* Suitable for plastic or glass fiber, RF, infra-red over free air or other media.
* Uses low cost LED and PIN combination to transmit and receive data.
* Additional operating mode to support PIN with integrated TIA.
* Asynchronous data rates from DC to 162kbps.
* Very low power consumption; typically 2 - 3mA, which could be extracted from the RS232 port itself, for > 12 dB link budget.
* Supports 3 additional low frequency asynchronous channels or the RS-232 handshake signals.
* Bit Error Rate (BER) < 10^-9
* Available in 44 pin TQFP (part no: ACS104A-TQ) and 28 pin PLCC (part no: ACS104A-PL) packages.
