DEI1016-PMS-G
The DEI1016 provides an interface between a standard avionics type serial digital data bus and a 16-bit-wide digital data bus. The interface circuit consists of a single channel transmitter with an 8X32 bit buffer, two independent receive channels, and a host programmable control register to select operating options. The two receiver channels operate identically, each providing a direct electrical interface to an ARINC data bus.

Attributes
Functional Description The DEI1016 provides an interface between a standard avionics type serial digital data bus and a 16-bit-wide digital data bus. The interface circuit consists of a single channel transmitter with an 8X32 bit buffer, two independent receive channels, and a host programmable control register to select operating options. The two receiver channels operate identically, each providing a direct electrical interface to an ARINC data bus.
The transmitter circuit contains an 8 word by 32 bit buffer memory and control logic which allows the host to write a block of data into the transmitter. The block of data is transmitted automatically by enabling the transmitter with no further attention by the host computer. Data is transmitted in TTL format on the D0(A)/D0(B) output pins. The signal format is compatible with DEI’s extensive line of ARINC 429 Line drivers for easy connection to the ARINC data bus.
