Serial IOs are widely used to expand the system bandwidth in communication systems. This paper provides an overview of serial IO design trade-offs with regard to power, cost, and performance. Circuit techniques are discussed to achieve low jitter and high bandwidth.

In the present technology development billions of transistors are fabricated on a single chip, which improves the performance of circuits in terms of high data transmission speed and power consumption. This requirement of data transmission speed is achieved with the help of high-speed transceivers. In this paper, we present a high-speed asynchronous wave-pipelined serializer and deserializer (SerDes) transceiver implemented using current-mode logic (CML). This asynchronous transceiver circuit does not require a clock and therefore it saves large amount of power which is consumed in the phase locked loop (PLL) and frequency synthesizer circuits. Further, the proposed design is built using CML which saves more power. CML circuit operates at relatively higher speed as compared to CMOS circuits which helps the circuit to operate at higher data rate. Compared to conventional CML latch, a novel CML latch is proposed in our design to increase the speed. The circuit is implemented in standard CMOS 65-nm technology. The total power consumed by the serializer and deserializer is 9.32mW, which is very less as compared to published related works. The proposed asynchronous SerDes transceiver operates at 18.1-Gbps data transmission rate with low power dissipation.

SuperB is a novel, high luminosity (10³⁶cm⁻²s⁻¹), asymmetric e+e− collider to be built at the University of Rome Tor Vergata, Italy. A detector and its associated electronics (ETD) will be installed in this facility. High-speed serial links will be used for trigger and clock distribution and for data read-out. Given the high luminosity of the accelerator, the on-detector ends of the links will have to cope with the expected radiation levels.

In this work, we present the results of irradiation tests on some candidate components for the electrical part of the links. We performed tests with a 62-MeV proton beam at INFN Laboratori Nazionali del Sud (Catania, Italy) and with a 60Co γ-ray source at ENEA, La Casaccia (Rome, Italy).
