HI-8475 Evaluation Board.
The Holt HI-8475 Evaluation Board demonstrates features of the HI-8475 ARINC 429 receiver IC. This device will decode 32 bit ARINC 429 words into parallel or serial format without the use of any software. The board and the HI-8475 can be run from a single 3.3V+/- 5% supply voltage. The HI-8475 and EVM (Evaluation Module) requires no software for control; all functions are set by hardware switches. Data can be filtered according to the label content of the ARINC word, using the LLA and FILT input setting and set with DIP switches. Other DIP switches configure the device speed, test modes etc.
