General Description The CT2500 provides a complete interface between the MIL-STD-1397 transceiver chip set (CT1698) and most microprocessor based systems.
The unit is monolithic and fabricated in CMOS technology, thereby having very low power requirements.
The unit handles all protocols of Type D & E interfaces including Burst Mode Data and forced EF functions.
Screened per individual test methods of MIL-STD-883.
Aeroflex Circuit Technology is an 80,000ft2 MIL-PRF-38534 certified facility in Plainview, N.

The unit can handle 16 bit and 32 bit data and command word loading.
In addition, data words can be preloaded into an external FIFO and the unit will load data words from the FIFO directly without subsystem intervention.
Similarly, data can be received and automatically loaded into a FIFO.
This frees up the subsystem until the data transfer is complet...
