ADK-1590, HI-1590 1553B Dual Transceiver With SPI Amplitude Control Evaluation Board

ADK-1590, HI-1590 1553B Dual Transceiver With SPI Amplitude Control Evaluation Board. The Holt HI-1590 Evaluation Board demonstrates features of the HI-1590 MIL-STD-1553B dual transceiver IC. This device transmits and receives Manchester encoded 20 bit MIL-STD-1553B serial data suitable bus transformers. Transceiver drive amplitude can be digitally adjusted from 0 to 26 Vp-p through the SPI interface. Adjustment can also be made with a 0 to 3.3VDC analog control signal, a potentiometer is provided for this. Amplitude controls for both buses are ganged together. In SPI mode, a low range option allows for more accurate amplitude adjustment from 0 to 4.9 Vp-p
