A E RO X LA ISO 9001 RTIFIE D I NC . General Description The CT1815 is a single hybrid micro-circuit which incorporates a serial encoder, transceiver, and Manchester decoder in one package. The encoder accepts serial NRZ data in conjunction with two synchronous clocks. This data stream is then Manchester encoded and maybe transformer coupled thru an external transformer to a 75 ohm tri-axial cable for transmission through up to 1000 feet of cable. The CT1815 receiver section accepts bipolar Manchester encoded signals and passes level detected signals to the serial decoder. The serial decoder reconstructs an NRZ data stream with derived clock. This allows the data to be processed by our CT2500 monolithic protocol chip for MIL-STD-1397 serial interfaces. All the input and output signals of the CT1815 are pletely patible with the CT2500. The CT1815 has a power management function. A transmitter standby mode is available to reduce the overall power consumption of the CT1815.
