Aeroflex ACT4438-1
ACT4438-1 is a next generation monolithic transceiver which provide full compliance with MIL-STD-1553/1760 and data bus requirements in a Bumped Chip Carrier™ (BCC++) with the lowest standby power consumption and single power supply operation. The Model ACT4438-1 performs the front-end analog function of inputting and outputting data through a transformer to a MIL-STD-1553/1760 data bus with a few external components. This results in low bit and word error rate with superior waveform purity and minimal zero crossover distortion.| Part No. | ACT4438-1 |

GENERAL DESCRIPTION
The Aeroflex Circuit Technology Model Design of these transceivers reflects particular attention to active filter performance. Efficient transmitter electrical and thermal design provides low internal power dissipation and heat rise at high as well as low duty cycles. Shown 2X NOTE: BCC++ and Bumped Chip Carrier are Trademarks of Fujitsu Ltd. Block Diagram (without Transformer) Transmitter The Transmitter section accepts bi-phase TTL data at the input and when coupled to the data bus with a 1:2.5 transformer, isolated on the data bus side with two 55 Ohm fault isolation resistors for direct stub coupling. The data bus signal produced for RISET = 2.7K Ohm is typically 7.5 Volts nominal P-P at A-A’, See Figure 5.
