1 Si6XXISO EVALUATION BOARD USER S GUIDE. Introduction The Si6xxISO evaluation board allows designers to evaluate Silicon Lab's 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 Silicon Laboratories 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 Si6x/x/x/x/x/6x include up to six unidirectional isolated channels, permitting data transmission up to 0 Mbps. The Si60x isolator series consists of single-package galvanic isolation solutions for I C, SMBus, and other digital power supply communications, including those for bus power management. For more information, refer to the respective family data sheets. A summary of the benefits provided by the Silicon Laboratories Si6xx CMOS Digital Isolator family includes: Si6xx Digital Isolators.0 kv,.7 kv, and.0 kv isolation ratings UL, CSA, and VDE certifications DC to 0 Mbps. to.

2 . Kit Contents The Si6xxISO Evaluation Kit contains the following items: Si6xxISO based evaluation board (Si6xxISO-EVB) shown in Figure. Si600, Si60, Si6, Si6, and Si66 CMOS digital isolators installed on the evaluation board Figure. Si6xxISO Evaluation Board Overview Rev. 0.

3 . Hardware Overview and Setup The Si6xxISO evaluation board is populated with the following isolators: Si600 (-channel I C isolator) Si60 (-channel digital isolator, -channel I C isolator) Si6 (-channel digital isolator, one forward, one reverse) Si (-channel digital isolator, five forward) Si66 (6-channel digital isolator, three forward, three reverse) The board is designed to be powered from two separate supplies (.. V, 00 ma) that power all the isolators on the board. VDD,GND and VDD,GND power the kv isolators. VDD,GND and VDD,GND power the and. kv isolators. Supplies as low as. 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 provides a silkscreen overview of the board. Figure. Si6xxISO Evaluation Board Silkscreen Rev. 0.

4 .. Digital Isolator Considerations The Si6xxISO evaluation board (see Figure ) provides a means of evaluating the Si6x,x,x,x,x,6x digital isolator families as well as the Si600 isolated I C family. After power (. V) has been supplied to the board, connect a digital input signal ( Vpeak max, with desired clock frequency up to 0 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 0, ±0%, 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 0 controlled impedance PCB traces. Figure illustrates the Si6 transmitting a 00 khz ( Vpeak) signal through the Si6. VDD and VDD were powered from V. Channel illustrates the input, and Channel illustrates the output. Figure. 00 khz ( V Peak) Signal Rev. 0.

5 .. I C Isolator Considerations After power ( V) has been supplied to the board, connect a digital square wave input ( Vpeak max, with desired clock frequency up to.7 MHz) to the desired input channel. The Si600/0 I C isolators have k pull-up resistors already installed. If these resistors are redundant with another board that is being used to evaluate the Si600/0, the user should remove the redundant pull-up resistors to accommodate adequate drive current for the test being performed. Figure illustrates Side B Pulling Up, with Side A following for the Si600. The Si600 was powered from V on both sides with a 00 khz input test signal. Figure. Side B Pulling Up, Side A Following Note: The test points in front of each device have mm spacing. If desired, the test points can be replaced with a mm spacing terminal block to assist in evaluation. Rev. 0.
