Description

The Aeroflex Circuit Technology model ACT4469D is a next generation monolithic transceiver which provides variable amplitude in compliance with H009 data bus requirements with the lowest standby power consumption available using three DC power supplies operation.

The dual channel model ACT4469D performs the front-end analog function of inputting and outputting data through a transformer to a H009 data bus.

Design of this transceiver reflects particular attention to active filter performance. This results in low bit and word error rate with superior waveform purity and minimal zero crossover distortion. The ACT4469D series active filter design provides the required H009 low harmonic distortion waveform without increasing the pulse delay characteristics significantly.

Efficient transmitter electrical and thermal design provides low internal power dissipation and heat rise at high and well as low duty cycles.The receiver input threshold is set internally.

Variable amplitude is adjusted with factory preset 010Vdc control line at 2 mA maximum input current at 10 Volts.
