General Description
CT1698 is a single hybrid microcircuit which incorporates a serial encoder, transceiver, and Manchester decoder in one package. The encoder accepts serial NRZ data in conjunction with two synchronous clocks. The CT1698 receiver section accepts bipolar Manchester encoded signals and passes level detected signals to the serial decoder. The CT1698 has a power management function and a variable drive level option. The transmitter standby mode is available to reduce the overall power consumption of the CT1698. The variable drive level output is externally programmable for testing purposes. Aeroflex Circuit Technology is a 80,000 square foot MIL-PRF-38534 certified facility in Plainview, N.Y.
