AE R O X LA ISO 9001 RTIFIED I NC . General Description CT1496-2 is a hybrid microcircuit which incorporates a low level serial Manchester encoder in a single package. The encoder accepts 32 bit parallel data and outputs a 35 bit Manchester encoded TTL NRZ serial stream (34 bit transmission if parity option is not selected). Preceding the 32 data bits are a synchronization and word identifier bit and a parity bit trails the data (parity is optional and may be disabled). A self-test feature is implementd allowing the user to verify transmit patterns. Aeroflex Circuit Technology is a 80,000 square foot MIL-PRF-38534 certified facility in Plainview, N.Y.
