A 5 Gb/s multi-mode transmitter with de-emphasis for PCI Express 2.0/USB 3.0

摘要

A versatile transmitter compatible SERDES system was fabricated in 55 nm CMOS technology. The proposed transmitter comprises a low-power and low-area driver with de-emphasis and a 10:1 serializer, meanwhile it supports power management to reduce the unnecessary dissipation and to complete the mode transition among four power modes. Furthermore, the transmitter is compatible with PCI Express 2.0/1.0 and also meets the USB 3.0 standard. The experimental results show this test chip passes PCI Express 2.0/1.0 TX compliance test and USB 3.0 TX compliance test. The chip occupies 0.033 mm~2 and consumes 33 mA at 5 Gb/s.
