WiMAX user data on the other hand is approximately 19Mbps per user channel and the C6455 DSPs can easily process multiple user channels. On the AMC-D4F1 three DSPs have a 32-bit 125MHz external memory interface connection to the FPGA, while one DSP has a 64-bit interface. That's at least a 4 Gbps interface which is sufficient for each DSP to process over 100 user channels.

Diode CR1 is usually of the heavy-duty variety because the value of resistor R is usually chosen so that the current through CR1 is rather high. This ensures that the bias to the transistor is stable. An alternative bias network is shown in Fig. 7-9. Here, two silicon diodes are used to forward bias an emitter-follower, which is used as a current amplifier. The voltage at the emitter of Q1 and, hence, at the base of Q2, is still 0.7V due to the VBE drop across transistor Q1. The RF choke and capacitor shown in both Figs. 7-8 and 7-9 are there only to prevent the flow of RF into the bias network.

However, the availability of closed formulation significantly reduces computing time. Therefore, an analytical model should necessarily offset drawbacks such as flexibility, complexity, tractability and computational performance.

Component values are selected on assumption that the Li-cell voltage ranges from 2.2 V to 3.6 V. Because that voltage serves as bias for the bridge and also as reference for the ADC, the ADC input and its full-scale output (span) move together as the cell voltage changes. This ratiometric configuration minimizes error and eliminates the need for a precision voltage reference.

Part 1 describes the basic structures of digital-to-analog convertors. Part 2 looks at interpolating DACs and sigma-delta DACs.

Therefore, a tool to evaluate WiMAX performance should, preferably, integrate both environments in the same software. This allows for a more complete interaction among models as different from mere parameter exchange.

Another development in DACs is the ability to make several on a single chip, which is useful to reduce PCB sizes and assembly costs. Today it is possible to buy sixteen 8-bit, eight 12-bit, four 14-bit, or two 16-/18-/20-/22-/24-bit DACs in a single package. In the future, even higher densities are probable.

• Help your engineers design green. The design phase is where you find the greatest ability to address environmental requirements. It is at the concept phase that designers must have access to the most up-to-date information on the material and substance makeup of the components and parts.
