CT1469-2 MIL-STD-1397 Type E 10MHz Transceiver Features • Low Level ±0.65V output • Optional transformer isolation • Internally set threshold • Operates with ±5 volt supply • Matched to 50 ohms system impedance power on or off • Bipolar construction for radiation resistance • Power management • Interfaces directly to the CT1496-2 (Manchester Encoder) and CT1508-2 (Manchester Decoder) • MIL-PRF-38534 compliant devices available CIRCUIT TECHNOLOGY www.aeroflex.com FLEX LA ISO 9001 CE R T I F I E D General Description CT1469-2 is a hybrid microcircuit which incorporates a MIL-STD 1397 Type E 10MHz transceiver in a single package. The transmitter section accepts 10MHZ serial Manchester encoded TTL NRZ data from the encoder and transformer couples a bipolar ±0.65 volt (nominal) signal level to a 50 ohm triaxial cable for transmission up to 1000 ft. The CT1469-2 receiver accepts a bipolar signal level and outputs an NRZ TTL serial data or SIS / SOS signal to the decoder (CT1508-2). Aeroflex Circuit Technology is a 80,000 square foot MIL-PRF-38534 certified facility in Plainview, N.Y.
