General Description
CT1508-2 is a hybrid microcircuit which incorporates a serial decoder in a single package. The encoder accepts a "N"
Bit (Typically 4, 34 or 35) serial Manchester encoded TTL NRZ signals and outputs a 4 bit SIS / SOS TTL output along
with "N" recovered data Bits/Clocks. Aeroflex Circuit Technology is a 80,000 square foot MIL-PRF-38534 certified
facility in Plainview, N.Y.
