- Page 1 3.4 Current Measurement ........................4 Appendix A ..............................5 Introduction The SiT6082EB evaluation board (EVB) is designed for use with SiTime’s XO in the 4-pin, 3.2 x 2.5 mm packages and LVCMOS output type. The SiT6082EB supports the following products:...
- Page 2 SMA output for direct connection to measurement equipment Probing points for accurate waveform measurement SiTime typically ships the EVB with the XO/SSXO/TCXO mounted using SiTime recommended reflow profile. The device should only be evaluated in its original soldered down state for best signal integrity and frequency stability.
- Page 3 Figure A1 Appendix Waveform Capturing Using Active Probe SiTime XO/TCXO is a high-speed logic output device. It is critical that the proper logic and high frequency measurement techniques are used along with the high-quality active probe to ensure best measurement results.
- Page 4 For waveform measurement, it's recommended to remove resistor R7. Please refer to Figure A2 for test point locations on the SiT6082EB. If the soldering probe is used, it is recommended to use C7 capacitor pads or solder it over it if necessary...
