General 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.

Serial Interface:
www.DataTShheeeDt4EUI.1co0m16 consits of two receive channels and one
transmit channel. Each receive channel operates
independently of each other and the transmitter. The
receive data is asynchronous to the transmitter data and
can also be at a different data rate than the transmitter.
Transmitter
The transmitter clock is free running and in phase with
the transmitter data. The transmitter data (DO(A) and
DO(B)) are TTL level signals. There are always at least
4 null bits between data words. An external ARINC line
driver is required to interface the transmitter to the
ARINC serial data bus. See ARINC 429 LINE
DRIVERS below.
Receiver
The receiver signals (DI(A) and DI(B)) are differential, bipolar,
return-to-zero logic signals. The ARINC channels can be
connected directly to the receiver with no external components.
ARINC 429 Line Driver
Device Engineering offers a complete line of ARINC line
drivers ICs that support the ARINC 429, 571, and 575
standards. Refer to DEI website at: http://www.deiaz.com.
