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.
