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.

Introduction
The specification detailed herein encompasses a hybrid transceiver designed to meet the requirements of STANAG 4153 and Type E requirements of MIL-STD-1397. The transceiver is transformer coupled to the specified triaxial cable and is available compliant to MIL-PRF 38534.
Electrical Requirements
See Figure 1 for block diagram. All input and output signals are manchester encoded. The transformer is internal to the package with its use being optional.
