Low Skew, 1-to-4 LVCMOS/LVTTL-to-3.3V LVPECL Fanout BufferICS8535-01General DescriptionThe ICS8535-01is a low skew,high performance 1-to-4LVCMOS/LVTTL-to-3.3V LVPECL fanout buffer.The ICS8535-01has two single ended clock inputs.the single ended clock input accepts LVCMOS or LVTTL input levels and translate them to 3.3V LVPECL levels.The clock enable is internally synchronized to eliminate runt clock pulses on the output during asynchronous assertion/deassertion of the clock enable pin.Guaranteed output and part-to-part skew characteristics make the ICS8535-01ideal for those applications demanding well defined performance and repeatability.6 7 89 1019 20 18 17 1612345V CC Q2nQ2V CC nc1314151211Q3nQ3V CC V EE CLK_ENQ 0n Q 0Q 1n Q 1V C Cn cC L K 0C L K _S E LC L K 1n c12345678910Q0nQ0V

6:Driving only one input clock.ICS8535-01 DATA SHEETAdditive Phase JitterThe spectral purity in a band at a specific offset from the fundamental compared to the power of the fundamental is called the dBc Phase Noise.This value is normally expressed using a Phase noise plot and is most often the specified plot in many applications.Phase noise is defined as the ratio of the noise power present in a 1Hz band at a specified offset from the fundamental frequency to the power value of the fundamental.This ratio is expressed in decibels (dBm)or a ratioof the power in the 1Hz band to the power in the fundamental.When the required offset is specified,the phase noise is called a dBc value,which simply means dBm at a specified offset from the fundamental.By investigating jitter in the frequency domain,we get a betterunderstanding of its effects on the desired application over the entire time record of the signal.It is mathematically possible to calculate an expected bit error rate given a phase noise plot.As with most timing specifications,phase noise measurements have issues.The primary issue relates to the limitations of the equipment.Often the noise floor of the equipment is higher than the noise floorof the device.This is illustrated above.The device meets the noise floor of what is shown,but can actually be lower.The phase noise is dependent on the input source and measurement equipment.N o i s e P o w e r (d B c /H z )Offset Frequency (Hz)Input/Output Additive Phase Jitter at 156.25MHz =0.09ps

requiring the use of a clock input,it can be left floating.Though not required,but for additional protection,a 1k Ωresistor can be tied from the CLK input to ground.LVCMOS Control PinsAll control pins have internal pullups;additional resistance is not required but can be added for additional protection.A 1k Ωresistor can be used.Outputs:LVPECL OutputsAll unused LVPECL outputs can be left floating.We recommend that there is no trace attached.Both sides of the differential output pair should either be left floating or terminated.Termination for 3.3V LVPECL OutputsThe clock layout topology shown below is a typical termination for LVPECL outputs.The two different layouts mentioned are recommended only as guidelines.The differential output is a low impedance follower output thatgenerate ECL/LVPECL compatible outputs.Therefore,terminating resistors (DC current path to ground)or current sources must be used for functionality.These outputs are designed to drive 50Ωtransmission lines.Matched impedance techniques should be used to maximize operating frequency and minimize signal distortion.Figure 2A and Figure 2B show two different layouts which arerecommended only as guidelines.Other suitable clock layouts may exist and it would be recommended that the board designerssimulate to guarantee compatibility across all printed circuit and clock component process variations.Figure 2A.3.3V LVPECL Output Termination Figure 2B.3.3V LVPECL Output TerminationICS8535-01 DATA SHEETSchematic ExampleFigure 3shows a schematic example of the ICS8535-01.In this example,the CLK0input is selected.The decoupling capacitors should be physically located near the power pin.For ICS8535-01,the unused clock outputs can be left floating.Figure 3.ICS8535-01Schematic ExampleICS8535-01 DATA SHEETPower ConsiderationsThis section provides information on power dissipation and junction temperature for the ICS8535-01.Equations and example calculations are also provided.1.Power Dissipation.The total power dissipation for the ICS8535-01is the sum of the core power plus the power dissipated in the load(s).The following is the power dissipation for V CC =3.3V +5%=3.465V ,which gives worst case results.NOTE:Please refer to Section 3for details on calculating power dissipated in the load.•Power (core)MAX =V CC_MAX *I EE_MAX =3.465V *50mA =173.25mW •Power (outputs)MAX =30mW/Loaded Output pairIf all outputs are loaded,the total power is 4*30mW =120mWTotal Power_MAX (3.465V ,with all outputs switching)=173.25mW +120mW =293.25mW 2.Junction Temperature.Junction temperature,Tj,is the temperature at the junction of the bond wire and bond pad and directly affects the reliability of the device.The maximum recommended junction temperature is 125°C.The equation for Tj is as follows:Tj =θJA *Pd_total +T A Tj =Junction T emperatureθJA =Junction-to-Ambient Thermal ResistancePd_total =T otal Device Power Dissipation (example calculation is in section 1above)T A =Ambient T emperatureIn order to calculate junction temperature,the appropriate junction-to-ambient thermal resistance θJA must be used.Assuming a moderate air flow of 200linear feet per minute and a multi-layer board,the appropriate value is 66.6°C/W per T able 6A below.Therefore,Tj for an ambient temperature of 70°C with all outputs switching is:70°C +0.293W *66.6°C/W =89.5°C.This is below the limit of 125°C.This calculation is only an example.Tj will obviously vary depending on the number of loaded outputs,supply voltage,air flow and the type of board (single layer or multi-layer).Table 6A.Thermal Resistance θfor 20-Lead TSSOP ,Forced ConvectionNOTE:Most modern PCB designs use multi-layered boards.The data in the second row pertains to most designs.Table

termination are shown in Figure4.Figure4.LVPECL Driver Circuit and TerminationT o calculate worst case power dissipation into the load,use the following equations which assume a50Ωload,and a termination voltage of V CC–2V.•For logic high,V OUT=V OH_MAX=V CC_MAX–0.9V(V CC_MAX–V OH_MAX)=0.9V•For logic low,V OUT=V OL_MAX=V CO_MAX–1.7V(V CC_MAX–V OL_MAX)=1.7VPd_H is power dissipation when the output drives high.Pd_L is the power dissipation when the output drives low.Pd_H=[(V OH_MAX–(V CC_MAX–2V))/R L]*(V CC_MAX–V OH_MAX)=[(2V-(V CC_MAX–V OH_MAX))/R L]*(V CC_MAX–V

货币霸主地位的形成，除了经济作为决定性因素，还有就是必须具备相应的历史条件。
人民币要获得霸主地位，必须具备三个条件：首先，中国必须成为全球唯一的经济强国，这至少还需要一百年的时间。
其次，中国必须成为全球创新力最强的国家。
目前中
包括政治、经济、文化、教育和科技等各个领域的创新机制的形成。
第三，必须具备相应的时机。
从目前来
看，由于中国的经济实力不及，这个机会只能眼睁睁看着从我们身边溜过。
除此，如果发达国家经济出现了大的衰退，新一轮科技革命又发生在中国，这也可能是一个难得的机会。
总之，一旦具备了这些条件，人民币称霸世界则是一种必然。
现在，就让我们来看看一国货币是如何称霸世界以及全球货币霸主地位是如何更替的。
世人皆知，
英镑之所以能够称霸世界，其根本原因是工业
国，加之其在全球推行殖民主义，推动英镑在人类历史上首次成为全球货币的霸主。
然而，后来英镑的霸主地位受到了挑战，特别是随着美国经济实力的增强，在1919至1939年期间，美元已
经与英镑并驾齐驱，二战的暴发却为美元独自称霸世界创造了条件。
本博主以为，只有当中国的复兴结束而成为世界唯一的经济强国，人民币才有称霸全球的可能。
当这个可能开始变为现实的时候，人民币还将与美元共同称霸世界一段时间之后，人民币才能获得全球货币的唯一霸主地位。
越来越强，其原因就在于人民币的国际化是中国经济发展的客观需要。
当人民币能够跨越国界，在境外流通，成为国际上普遍认可的计价、结算及
储备货币时，中国也就进入了一个新的复兴阶段。
但人民币的国际化并不意味其霸主地位的形成。
那么，人民币有称霸世界的可能吗？
在人类历史上，只有两种货币称霸世界，一是英镑，二是美元，这也决定了全球货币霸主地位只进行过一次更替，那就是美元取代英镑而称霸世界至今。
1939年以后，随着英国在二战战场上节节败退，美国却借机大发战争财，一下超越了英国，尤其是二战结束以后，美国的经济实力达到顶峰，成为全球唯一的经济强国，由于英国等欧洲国家面临着战后重建，资金非常短缺，不得不求助于美国。
此时，聪明的美国人乘机建立布雷顿森林体系，美元直接与黄金挂钩，各国货币则与美元挂钩，并以金本位为基础建立新的国际汇率和贸
易体系。
元纸币，形成了以美元为中心的循环，欧洲各国之间也开始用美元进行结算，由此推动了美元作为全球唯一货币霸主地位的形成。
后来，由于美国成为全球科技与金融创新力最强大的国家，尽管遭遇了许多坎坷，但并没有动摇美元的霸主地位。
