Introduction
The SiT6092EB evaluation board (EVB) is designed for use with SiTime's VCXO in the 6-pin 7.0 x 5.0 mm
packages and LVCMOS output type.
The SiT6092EB supports the following products:
Base Part Number
SiT3807
SiT3808
SiT3809
SiT3907
EVB Features
-
Support for all device configuration modes: VCXO, DCXO
-
SMA output for direct connection to measurement equipment
-
Probing points for accurate waveform measurement
SiTime typically ships the EVB with the VCXO/DCXO 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. The device performance is not guaranteed if it is de-soldered and then re-soldered
either manually or via reflow process.

  • Page 1 3.4 Current Measurement ........................5 Appendix A ..............................6 Introduction The SiT6092EB evaluation board (EVB) is designed for use with SiTime’s VCXO in the 6-pin 7.0 x 5.0 mm packages and LVCMOS output type. The SiT6092EB supports the following products:...
  • Page 2 EVB Usage Descriptions EVB Configurations SiT6092EB can be configured to support two configuration modes including XO with output enable (OE), XO in Standby (ST), 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.
