Solutions Different forms of the traditional model, with TektronixDSA8200 digital signal analyzer, 80E08TDR modules and IConnect Software Implementation of the model proved very successful. Iconnect software can help according to the measured TDR data to create visible graphics at the same time find out the actual measured the eye of the correspondence.
Advantage IConnect use of the software has enabled Freescale Semiconductor measurement results can be extracted directly from the package of non-continuous feature. In addition to the package model, but also to help draw the Freescale chip parasitic behavior and Tx / Rx resistance of the actual end
Background description Many companies have used a very strong performance of the transmitter power and created a lot of brilliant achievements. Development has made new breakthroughs in the content of their core design is the implementation of new standards. However, under certain circumstances, to the transmitter in the modeling, understanding the potential transmission engineers measuring standards will be confused. Freescale Semiconductor against
Car , Consumption devices, industrial and embedded networking market, semiconductor design and manufacture of leading the world, find new ideas, and with Tektronix unique IConnect software modeling method with the existing transmitter is associated.
Freescale Semiconductor's signal integrity engineers NareshDhamija said: "With IConnect software in different ways we can achieve our way, this is really amazing. Design team can now see the actual Tx / Rx chip end resistance and the substrate / package intermittent situation. "He added:" Using Iconnect software, can be extracted based on the measurement model, different from the pure extract from the simulation model, this model closer to actual silicon. " Freescale Semiconductor
use TektronixIConnect modeling software for the transmitter
DSA8200TDR platforms at the time, IConnect software is an efficient, easy to use and cost-effective solution that can be measured on the basis of gigabit interconnect links and devices for performance evolution, including signal integrity analysis, impedance , S parameters and the visible graphics test and fault isolation.
Process Figure 1 shows the measurement test set. Here, the gray area of each component is part of the transmitter in the probe with TDR measurements using the Tektronix DSA8200 IConnect software testing can be used as plant equipment.
Using this setting, TDR and the transmitter produces 100mVpk-pk amplitude of 1010 ....( clock format) as input to the 80E08 sampling head, and achieved an average of 300 DSA8200 collection points to the transmitter filter switching noise. Captured by the above input to Zo as the reference cited to calculate the Z line is 50 Euro. Impedance contour line shown in the left-most 50 in Europe, the far right in Europe to 42.5, that the transmitter output impedance, Figure 3 shows IConnect captured. TRD measurement probe from the side view, the input impedance for the transmitter. DUT see the other side - from the launch to see for the output impedance side.
To see the output impedance, Z line to be overturned, as the simulation input, but the simulation does not accept the Z line as input. Actual DUT's flip Z line was very good and can be used for future reference. For input, we will turn DUT voltage waveform, and called flip DUT. Then, a brief reference on the same lead and Zo reference cited, we have calculated the Z flip DUT line voltage waveform, the input impedance of the transmitter obtained 42.5 Europe, rather than 50 euro. This is shown in Figure 3, the actual flipping Z line of the same DUT. I am China Suppliers writer, reports some information about discount pillar candles , led votive candles.
