Abstract

A key challenge in optical networking is the development of low-power transceivers that interface to optical sub-assemblies (TOSAs & ROSAs). While SiGe technologies are often selected for jitter performance with optical links, especially on the egress path to the transmit optics, lower-power and higher levels of digital integration often result from CMOS approaches [1]. This paper describes a generic CMOS 25-to-30Gb/s SerDes for use within CDR or gearbox applications, targeting the draft requirements of the OIF 28G-VSR standard [2] and suitable for both 100GBASE-LR4/OTL4.4 gearbox and retiming applications, including CFP and CFP2 [3].

Abstract

A DSP-based low-power 12.5Gb/s SerDes using a baud-rate ADC and a digital data-path is developed for backplane data communication. A digital 2-tap FFE and a 5-tap DFE in the RX provide channel compensation. A BER of

Abstract

Response of hammer foundations to the blows of the head is analyzed allowing for the uplift of both the anvil and the foundation block. Damping as well as stiffness of the system are accounted for in a rational way. The validity of the response prediction on the basis of the standard theory in which uplift is omitted, is examined. One and two mass systems are considered. The theory is compared with the results of tests conducted with a hammer foundation in operation.
