Oscilloscope probes are attached to RO, A, and B. The EVAL-ADN469xEHDEBZ allows the ADN4690E/ ADN4691E/ADN4694E/ADN4696E to be quickly and easily evaluated. The evaluation board allows all of the input and output functions to be exercised without the need for external components. Jumper configurations are shown in Table 2. EVALUATION WITH APPLICATIONS Two EVAL-ADN469xEHDEBZ boards can be connected together in a point-to-point configuration as shown in Figure 4. In order to allow part evaluation with a load equivalent to a parallel-terminated bus, the boards have been fitted with 50 Ω termination resistors. For the point-to-point configuration in Figure 4, these should be replaced with resistors of 100 Ω. The board is powered by connecting a 3.3 V power supply to the screw terminals for VCC and GND. Supply current is typically 16 mA with both driver and receiver enabled, or 1 mA with both disabled. A 10 µF decoupling capacitor, C1, is fitted at the connector between VCC and GND. The VCC pin of the ADN469xE is fitted with a decoupling capacitor of 100 nF. A signal generator is connected onto one board’s DI input. This boards A and B outputs are respectively connected to the second board’s A and B inputs. An example evaluation of the ADN4690E/ADN4691E/ ADN4694E/ADN4696E driver is shown in Figure 2. A signal generator is connected to DI with an input signal of 50 MHz (ADN4690E/ADN4694E) or 100 MHz (ADN4691E/ ADN4696E), with a 50% duty cycle and swing of between 0 V and 3.3 V. Jumpers LK1 and LK2 are connected in Position A to disable the receiver and enable the driver. Oscilloscope probes are connected to DI, A, and B. Connecting probes to DI on the first board, and A, B, and RO on the second, the propagation of the input signal across the bus and to the receiver output of the second board can be observed and evaluated. Alternatively, the EVAL-ADN469xEHDEBZ can be connected to an existing bus and a control board as shown in Figure 5 in order to test the performance in the application. In this case, both termination resistors should be removed, as well as the jumpers on LK1 and LK2. Control signals should be connected to RO, RE, DE, and DI. Similarly, an evaluation of the ADN4690E/ADN4691E/ ADN4694E/ADN4696E receiver is shown in Figure 3. A signal generator capable of applying a differential input signal is connected to J5 and J6, with the input swing between 1 V and 1.2 V (J6 input the inverse of J5 input).
