General Description:
The DEI 1016 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 inde-
pendent receive channels, and a host programmable control register to select operating options. The two re-
ceiver 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 trans-
mitter with no further attention by the host computer. Data is transmitted in TTL format on the D0(A)/D0(B) out-
put pins. The signal format is compatible with DEI’s extensive line of ARINC 429 Line drivers for easy connec-
tion to the ARINC data bus.
