A 24-Gb/s 27 - 1 Pseudo Random Bit Sequence Generator IC in 0.13 μm Bulk CMOS

This work presents a 24Gb/s pseudo random bit sequence (PRBS) generator with a sequence length of 2
⁷
- 1. The circuit uses an interleaved linear feedback shift register and multiplexing architecture. An output voltage swing of 280mVpp is achieved for 24Gb/s data rate and 390mVpp for 10Gb/s. The circuit features a trigger output which allows to trigger the eye or the sequence pattern. The circuit is manufactured in 0.13 mum bulk CMOS technology and draws 183 mA at 1.5 V supply voltage
