Introduction

The SiT6096EBB evaluation board provides the ability to evaluate the functionality of the SiTime low-
frequency oscillators on a simple board that makes it easy to power up the oscillator and observe the
output buffered through an operational amplifier. The analog buffer isolates the device from the
significant loading, which is important for performing best waveform and current measurements.
The SiT6096EBB evaluation board supports 1 Hz to 32.768 kHz oscillators in a 2.0 x 1.2 mm x mm QFN
package including the following products:

    The analog buffer isolates the device from the significant loading, which is important for performing best waveform and current measurements. The SiT6096EBB evaluation board supports 1 Hz to 32.768 kHz oscillators in a 2.0 x 1.2 mm x mm QFN package including the following products:...
  • Page 2: O Descriptions

    The oscillator output is best observed using buffered output path through point the SMA connector J1. The buffer can be disconnected, and the output can be directly observed using test point. SiT6096EBB User Manual | Rev 2.0 Page 2 of 9 www.sitime.com...

    SiT6096EBB Evaluation Board User Manual EVB Usage Descriptions EVB Configurations SiT6096EBB supports multiple configurations for evaluating AC and DC coupled output modes of SiTime oscillator. In addition, this EVB provides the ability to add additional load capacitance and to bypass the output buffer.
  • Page 4: Buffered Clock Output

    To get full amplitude result must be multiplied by 2. When using direct output configuration SiTime recommends active probes with 10 MΩ and <1 pF impedance for proper clock waveform measurement. A passive voltage probe is not recommended as it adds a high capacitive load to the part and the long ground lead clip is not suitable.
  • Page 5: Measuring Jitter

    SiT6096EBB Evaluation Board User Manual More details on the SiTime recommendations on the oscillator’s output probing can be found in AN10028. Measuring Jitter The analog buffer isolates the device from the significant loading, which is important for best jitter measurement result. The R2 can be populated as 0 Ω resistor for best result.
