SI86XXISO-KIT

Si 86xxI SO- EVB UG Si8 6 XX ISO E VALUATION B O A R D U S E R ’ S G U I D E 1. Introduction The Si86xxISO evaluation board allows designers to evaluate Skyworks family of CMOS ultra-low-power isolators. These isolators are CMOS devices employing RF coupler technology to transmit digital information across an isolation barrier. Very high speed operation at low power levels is achieved. These products are based on Skyworks’ proprietary RF isolation technology and offer shorter propagation delays, lower power consumption, improved noise immunity, smaller installed size, and more stable operation with temperature and age versus opto couplers. The Si861x/2x/3x/4x/5x/6x include up to six unidirectional isolated channels, permitting data transmission up to 150 Mbps. The Si860x isolator series consists of single-package galvanic isolation solutions for I2C, SMBus, and other digital power supply communications, including those for bus power management. For more information, refer to the respective family data sheets.

Hardware Overview and Setup The Si86xxISO evaluation board is populated with the following isolators: Si8600 (2-channel I2C isolator) Si8605 (2-channel digital isolator, 2-channel I2C isolator) Si8621 (2-channel digital isolator, one forward, one reverse) Si8455 (5-channel digital isolator, five forward) Si8663 (6-channel digital isolator, three forward, three reverse) The board is designed to be powered from two separate supplies (2.5–5.5 V, 500 mA) that power all the isolators on the board. VDD1,GND1 and VDD2,GND2 power the 5 kV isolators. VDD3,GND3 and VDD4,GND4 power the 1 and 2.5 kV isolators. Supplies as low as 2.5 V can be used. If a user wants to evaluate an isolator other than the ones populated, this can be accomplished by removing the footprint-compatible device installed on the evaluation board and replacing it with the desired isolator device. Figure 2 provides a silkscreen overview of the board. Figure 2.

Digital Isolator Considerations The Si86xxISO evaluation board (see Figure 1) provides a means of evaluating the Si861x,2x,3x,4x,5x,6x digital isolator families as well as the Si8600 isolated I2C family. After power (2.5–5 V) has been supplied to the board, connect a digital input signal (5 Vpeak max, with desired clock frequency up to 150 Mbps) to the desired input channel. To view the isolated channel’s data transmission, connect a scope probe to the output channel of interest. There are various inputs and outputs on either side of the board depending on the device one chooses to evaluate, as indicated by the silk screen. The board can be used to measure propagation delay, pulse-width distortion, channel-channel matching, pulse-width skew, and various other parameters. The nominal output impedance of an isolator driver channel is approximately 50 , ±40%, which is a combination of the values of the on-chip series termination resistor and the channel resistance of the output driver FET. When driving loads where transmission line effects are a factor, output pins should be terminated with 50  controlled impedance PCB traces. Figure 3 illustrates the Si8621 transmitting a 500 kHz (3 Vpeak) signal through the Si8621. VDD1 and VDD2 were powered from 3 V. Channel 1 illustrates the input, and Channel 2 illustrates the output.

I2C Isolator Considerations After power (3–5 V) has been supplied to the board, connect a digital square wave input (5 Vpeak max, with desired clock frequency up to 1.7 MHz) to the desired input channel. The Si8600/05 I2C isolators have 1 k pull-up resistors already installed. If these resistors are redundant with another board that is being used to evaluate the Si8600/05, the user should remove the redundant pull-up resistors to accommodate adequate drive current for the test being performed. Figure 4 illustrates Side B Pulling Up, with Side A following for the Si8600. The Si8600 was powered from 3 V on both sides with a 100 kHz input test signal. Figure 4. Side B Pulling Up, Side A Following Note: The test points in front of each device have 1 mm spacing. If desired, the test points can be replaced with a 1 mm spacing terminal block to assist in evaluation.
