- Page 1 3.4 Current Measurement ........................4 Appendix A ..............................5 Introduction The SiT6095EB evaluation board (EVB) is designed for use with SiTime’s XO in the 4-pin, 2.0 x 1.6 mm packages and LVCMOS output type. The SiT6095EB supports the following products:...
- Page 2 EVB Usage Descriptions EVB Configurations SiT6095EB can be configured to support three configuration modes including XO/TCXO with output enable (OE), XO in Standby (ST), Spread Disabled (SD), Voltage Control (VC) or Digital Control (DC). Oscillator output can be accessed in several ways listed in Table 2. Table 2 describes components configuration to support all output configurations.
- Page 3 For waveform measurement, it's recommended to remove resistor R7. Please refer to Figure A2 for test point locations on the SiT6095EB. If the soldering probe is used, it is recommended to use C7 capacitor pads or solder it over it if necessary (Figure SiT6095EBB User Manual | Rev 3.01...
- Page 4 Figure 1: Recommended points for soldering probe head More details on the SiTime recommendations on the oscillator’s output probing can be found in AN10028. Measuring Jitter and Phase Noise For Jitter measurements or phase noise measurements with evaluation boards, SiTime recommends using SMA support Configuration to connect the device output directly to external equipment, such as Time Interval Analyzer (TIA) or high-bandwidth real-time oscilloscope.
