104Gb/s 2"-1 and 110Gb/s 2-1 PRBS Generator in InP HBT Technology

HaLoS – Integrated RF-Hardware Components for Ultra-Wideband Localization and Sensing

“…Early high-speed PRBS generators for high data rates have been employed in III/V HBT technologies [28]. Moreover, a 110 Gb/s PRBS generator has been published in [29] using InP HBT technology with a transit frequency ( T f ) more than 300 GHz. Recently, several PRBS generator circuits have been published in SiGe bipolar technology for test purposes in fiber-optic communications.…”

Flip-chip mounted 1:4 demultiplexer IC in InP DHBT technology operating up to 100 Gb/s

“…8. The test pattern was produced by an inhouse 2 9 -1 PRBS generator IC [4] placed in a probe station. The data was transferred to the packaged DEMUX through a 30 cm long semi-rigid V-cable.…”

“…We have previously presented a 4:1 MUX [2], a 1:4 DEMUX [3], 2 9 -1 and 2 11 -1 PRBS generators [4], and a bit-error detector for 2 9 -1 PRBS [5], all operating at 100 Gb/s or above 1 .…”

A 100-Gb/s 1:4 Demultiplexer in InP DHBT Technology

“…V connector probes and V connector cables were used for all the high speed clock and data signals. To generate the input signal, an in-house developed PRBS 29-1 InP DHBT chip was used [7]. This chip is not packaged so it is also wafer probed.…”

“…It is part of a project which aims to design a chipset for a 100-Gb/s electrical transceiver demonstrator. Details on the different chips can be found in [6][7][8].…”
