The ADN4650 employs Analog Devices, Inc., iCoupler® technology to combine a 2-channel isolator with an LVDS receiver and driver into a single, 20-lead wide body SOIC package. The ADN4650 is capable of running at data rates of up to 600 Mbps with very low jitter. The evaluation board has separate ground and power planes for each side of the isolator. This separation enables the evaluation of the ADN4650 with galvanic isolation between both sides of the device. Jumper-selectable power supplies at 3.3 V or 2.5 V are required on each side of the ADN4650. An on-chip LDO can provide 2.5 V using an external 3.3 V power supply.

SMA connectors expose all LVDS inputs and outputs (see Table 2 and Table 3). Connect a signal generator using the J1 and J2 connectors and set up a 300 MHz square wave clock with an amplitude of 350 mV and an offset of 1.2 V. Connect the oscilloscope directly to the J5 and J6 connectors to perform timing measurements including propagation delay and skew. Precision measurements, for example, jitter, using a differential probe requires attaching the probe at the TP7 and TP8 test points (or TP9 and TP10 for Isolator Channel 2) and potentially cutting the traces to the connectors to minimize reflections. Figure 2. DOUT1− and DOUT1+ with a 300 MHz Clock, Single-Ended and Differential 13761-003 When using a 3.3 V power supply, VIN1 and VDD1 (Pin 1 and Pin 3 on the ADN4650) are bypassed to GND1 on the board using 1 µF capacitors (C18 and C2, respectively). VIN2 and VDD2 (Pin 20 and Pin 18 on the ADN4650) are bypassed to GND2 on the board using 1 µF capacitors (C19 and C6, respectively). When using a 2.5 V power supply, VIN1 or VIN2 connects directly to VDD1 or VDD2 by shorting Jumpers P4 or P7, respectively. Both VDD1 pins are also bypassed to GND1 with 0.1 µF capacitors (C1 and C4). Both VDD2 pins are also bypassed to GND2 with 0.1 µF capacitors (C5and C7). 13761-002 On the EVAL-ADN4650EB1Z, the power supplies are configured using Jumpers P4 and P7 (see Table 1) and are connected to the J9 and J10 SMA connectors (see Table 2 and Table 3). A 3.3 V power supply can be applied to Side 1 and/or Side 2 of the ADN4650 by removing Jumpers P4 (Side 1) and P7 (Side 2). If a 2.5 V power supply is connected, insert the relevant jumper must (P4 for Side 1 and P7 for Side 2). At 300 MHz with a load resistance of 100 Ω, the maximum operating current from each power supply is 72 mA. Figure 3. DOUT2− and DOUT2+ with a 300 MHz Clock, Single-Ended and Differential Figure 2 shows a plot of the oscilloscope connected via the J5 and J6 connectors. Oscilloscope Channel 3 (green) and Channel 4 (purple) show the J5 and J6 connectors separately (single-ended) with the differential signal (orange). Figure 3 shows an operation of the second isolated LVDS channel. In contrast to Figure 2, the signal generator connects via the J3 and J4 connectors and the oscilloscope connects to the J7 and J8 connectors. Oscilloscope Channel 3 (green) and Channel 4 (purple) show the J7 and J8 connectors separately (single-ended) with the differential signal (orange).

Test Setup for EN 55022 Radiated Emissions Testing Radiated emissions testing is performed at an independent external test facility with the EVAL-ADN4650EB1Z. Evaluating the EVAL-ADN4650EB1Z to the EN 55022 standard is undertaken in a 10 m radiated emissions test chamber using the test setup shown in Figure 5. The setup comprises a battery-powered EVAL-ADN4650EB1Z connected to a signal generator located outside the chamber via coaxial cables. As specified by the EN 55022 standard, both horizontal and vertical peak scans are undertaken with any visible emissions peaks investigated using quasi-peak detector measurement. For each frequency measured using a quasi-peak detector, the device under test rotates through 360 degrees to find the worst case angle. The receiving antenna then elevates from 1 m to 4 m in height to find the worst case elevation. The worst case quasi-peak measurements are compared to the EN 55022 Class B and Class A limits. The test results are shown in Table 4; a classification report is available on request (please contact Analog Devices or the component distributor for support). Radiated emissions are measured across 30 MHz to 1 GHz and from 1 GHz to 3 GHz. With a 600 Mbps PRBS7 input, the EVAL-ADN4650EB1Z passes the EN 55022 Class B limits. With a 300 MHz clock input, the EVAL-ADN4650EB1Z passes the EN 55022 Class A limits. To pass the Class B limits when isolating high frequency clocks, reduce the printed circuit board (PCB) clearance from the 8 mm implemented on EVALADN4650EB1Z to, for example, 2 mm. Table 4.
