HI-1590
MIL-STD-1553/1760
3.3V Monolithic Dual Variable Transceiver
DESCRIPTION
The HI-1590 is a low power CMOS dual +3.3V transceiver with
the ability to vary the amplitude of the transmitter outputs. It is
designed to meet the requirements of the MIL-STD-1553 /
1760 specifications, and is pin compatible to the HI-1570. The
HI-1590 adds SPI communication to the onboard DAC to vary
the amplitude of the transmitter outputs.
The transmitter section of each bus takes complementary
CMOS / TTL Manchester II bi-phase data and converts it to
differential voltages suitable for driving the bus isolation
transformer. Separate transmitter inhibit control signals are
provided for each transmitter. The user has the option to either
supply an external voltage to a single analog input pin, or
program an 8-bit DAC through a SPI port to control the
transmitter output amplitude.
The receiver section of each bus converts the 1553 bus bi-
phase differential data to complementary CMOS / TTL data
suitable for inputting to a Manchester decoder. Each receiver
has a separate enable input which can be used to force the
output of the receiver to a logic “0“.
To minimize the package size for this function, the transmitter
outputs are internally connected to the receiver inputs so that
only two pins are required for connection to each coupling
transformer.
