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.Y.
