Preliminary
The MC740-430E is an engineering sample of 47-Gb/s signal generator. It consists of a 4:1
multiplexer (MUX), D-type flipflop (D-FF), and clock distribution unit based on 0.1-µm InP-HEMT
devices. Four-parallel data inputs are multiplexed to 47-Gb/s data by using 47- and 11.75-GHz
clock signals. At the output stage, the D-FF regenerates the muliplexed data with the 47-GHz clock
signal and offers symmetrical eye openings. The MC740-430E has SCFL (Source Coupled FET
Logic) I/O and can be directly connected to a pulse pattern generator.
FEATURES
Operating range:
38 to 47 Gb/s (min.) (note)
Signal regeneration with full-rate clock signal
Large output amplitude:
SCFL I/O (VOHD = 0V, VOLD = -0.9V, typ.)
Single power supply voltage: DC -6 V
(note) 50-Gb/s operation is optional.
APPLICATIONS
Parallel-to-serial converters, Test equipments
