FIFO memory for coupling frequency independent systems - is made in gallium arsenide, ELL etc. technique, permitting frequency conversion

摘要

Frequency independent electric systems are coupled by a FIFO memory, realised in a GaAs, ECL, etc., technology. Thus a frequency conversion is possible even at very high writing or read-out frequencies. If realised in an ECL technology, the FIFO memory is capable of data processing up to the writing or read-out frequencies of 350 MHz. At the inputs or outputs of the FIFO memory is fitted a translator as logic converter for level variation. The logic converter may be in the form of an ECL to TTL, or TTL to ECL logic. The logic converter and the FIFO memory may form an integral unit. USE/ADVANTAGE - For dual port RAM(s) with extension up to high frequencies.
