... It offers a –3 dB signal bandwidth greater than 200 MHz and channel switch times with 0.1% settling. With – crosstalk and –105 dB of isolation (@ 5 MHz), the AD8116 is useful in many high speed applications. The differential gain and differential phase errors of better than 0.01% and 0.01°, respectively, along with 0 ...

... AD8116 is shown in Figure 4. In normal operation, the DATA OUT pin of one AD8116 is connected to the DATA IN of the next. In this way, for example, an array of eight AD8116s would be programmed with one 640-bit sequence. In this mode CE is logic low and the CLK and UPDATE pins are connected in parallel ...

... ORing at the output to only four outputs. This will prevent an enabled output from having to drive a large number of disabled devices. Additionally, by using the lower eight outputs from each of the two Rank 2 AD8116s, a blocking 128 × 32 crosspoint array can be realized. There are, however, some drawbacks to this technique. The offset voltages of the various cascaded devices will accumulate and the bandwidth limitations of the devices will compound ...

... Power-On Reset Most systems will want all the AD8116s the reset state (all outputs disabled) when power is applied to the system. This ensures that two outputs that are wire-ORed together will not fight each other at power up ...

... As a crosspoint system or device grows larger, the number of theoretical crosstalk combinations and permutations can become extremely large. For example, in the case of the 16 × 16 matrix of the AD8116, we can examine the number of crosstalk terms that can be considered for a single channel, say IN00 input. IN00 is programmed to connect to one of the AD8116 outputs where the measurement can be made ...

... In addition, the load resistor actually lowers the crosstalk com- pared to the conditions of the AD8116 outputs driving a high impedance (greater than 10 kΩ) or driving a video load (150 Ω). This is because the electric field crosstalk that dominates in the high impedance case has a phase of – ...

... As can be seen in Figure 17, there is extensive power supply decoupling on the evaluation board. Figure 17 shows the location of all the decoupling capacitors relative to the AD8116’s pins. Four large 10 µF capacitors are located near the evaluation board’s power supply connection terminals. ...
