ACS104A Data Sheet

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.

Equivalent Block Diagram of ACS104A

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.

The ACS104A 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.

The ACS104A employs data compression and time compression techniques,

affording high launch power in short bursts, leading to a low average power

consumption. The advantage of this approach is that high link budgets can be

achieved with inexpensive optical components. For example, the recommended

set-up for RS-232 applications (19.2kbps + handshake signals) assumes that the

LED is driven with a peak current of approximately 15.4mA for 6 % of the time.

The machine cycle is short enough to facilitate power supply smoothing with a

small external capacitor in the region of 100µF.
