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.  
The ACS102A 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.
