10 GBIT/S WORD GENERATOR BASED ON SILICON BIPOLAR CIRCUITRY A. Felder1,2), P. Weger1.2), R. Scheidl2>, K. Ehinger2), E. Bonek1) ABSTRACT A 10 GBit/s word generator has been built around bipolar silicon circuitry. The basic data rate is tunable from about 100 Mbit/s.The maximum basic data rate is as high as 2.8 GBit/s, which is boosted by only two stages of 2: 1 multiplexing to the new record valu
