摘要： A conventional hydride VPE reactor is modified by the addition of a gas switching manifold and the use of three way pneumatic valves in the manifold to alternately direct the flow of reactant gas mixtures into either the reactor or a vent line. With these additions, various predetermined gas mixtures of arsine, phosphine, and hydrogen selected by electronic mass flow controllers (GM1 and GM2) and predetermined gas mixtures of H.sub.2 and HCl (GM3) may be alternately infused into the reactor chamber or vented as desired. When GM3 is injected into the reactor chamber, the content of GaAs of the growing layer increases while the content of In decreases. Given this, when GM3 and GM2 are vented rather than injected into the furnace and GM1 is directed into the furnace, a layer of InGaAsP with a predetermined composition (A) will be deposited. Alternatively, when GM3 and GM2 are co-injected into the reactor and GM1 is be directed to the vent, a layer of InGaAsP of a predetermined composition (B) will be deposited. Therefore, the flow rates of HCl, PH.sub.3 and AsH.sub.3 can be adjusted to produce compositions A and B that correspond to a lattice-matched condition with either InP or GaAs substrate.
摘要翻译：传统的氢化物VPE反应器通过添加气体切换歧管和在歧管中使用三通气动阀来交替地将反应气体混合物的流动引导到反应器或排气管线中来进行修改。通过这些添加，可以将电子质量流量控制器（GM1和GM2）选择的各种预定的胂，膦和氢的气体混合物和H 2和HCl（GM 3）的预定气体混合物交替地输入到反应器室中或根据需要排气。当GM3被注入到反应器室中时，生长层的GaAs含量增加，而In的含量减少。考虑到这一点，当GM3和GM2排放而不是注入炉中，GM1被引入炉中时，将沉积具有预定组成（A）的InGaAsP层。或者，当将GM3和GM2共注入到反应器中并且GM1被引导到排气口时，将沉积预定组成（B）的InGaAsP层。因此，可以调节HCl，PH3和AsH3的流量，以产生与InP或GaAs衬底的晶格匹配条件相对应的组分A和B.

摘要： A method to calibrate an equalizer for communicating signals over a data link between a transmitter and receiver includes measuring loss in the link and automatically determining a multi-tap equalization setting for the transmitter based on the measured loss. The multi-tap equalization setting may be determined using a look-up table, which stores a plurality of equalization settings for a respective number of link loss values. Once the equalization setting matching the measured link loss is found in the table, the equalizer can be optimally set to reduce or eliminate intersymbol and other types of interference.

摘要： According to some embodiments, time domain reflectometry based transmitter equalization is provided. For example, a reflection detector in a transmitter may detect a reflection signal associated with a calibration signal that was transmitted via an interconnect. The reflection detector may then provide filter information to a transmitting unit to facilitate a transmission of data to a remote receiver via the interconnect. According to some embodiments, the receiver adjusts a termination impedance before the calibration signal is transmitted.

摘要： A technique to simultaneously reduce high-frequency insertion loss and cross-talk for a multi-layered add-in card is disclosed. The technique is based on selective removal of ground and power planes beneath the edge fingers. This selective removal of power and ground planes removes excess capacitance at the edge fingers, lowering the insertion loss at high frequencies, while maintaining an impedance match with an associated connector. Simultaneously, the leftover metallic ground/power plane provides electromagnetic shielding and thus reduces the cross-talk between the differential pairs. Optimum performance of the connector with minimized insertion loss and cross-talk can be obtained for high-speed analog and digital applications.
摘要翻译：公开了同时降低多层附加卡的高频插入损耗和串扰的技术。该技术基于选择性地去除边缘手指下方的地面和电源平面。电源和接地层的这种选择性去除消除了边缘手指处的过剩电容，降低了高频下的插入损耗，同时保持与相关连接器的阻抗匹配。同时，剩余的金属接地/电源平面提供电磁屏蔽，从而减少差分对之间的串扰。对于高速模拟和数字应用，可以获得具有最小插入损耗和串扰的连接器的最佳性能。
