ASGTX Evaluation Board ASGTX-Eval ASVMP Moisture Sensitivity Level – N/A Pb RoHS/RoHS II compliant 37.56 x 42.66mm Low Jitter High ASGTX Evaluation boards are designed to facilitate engineering evaluation of the ASGTX series of Performance high frequency VCTCXO’s. These boards are pre-configured to test the ASGTX oscillator with an LVDS output. As shown in section-6 (schematic), R8 is pre-populated with a 100Ω resistor. DESCRIPTION: Further, to complete the path to the SMA output connectors, R3 & R6 are populated with 0Ω resistors. To test the LVCMOS output, simply remove R8 and monitor the output at OUT SMA Connector. To test the LVPECL output, simply remove R8, and solder down the following resistors as a function of the supply voltage, VDD.
