    The resistor network can be configured such that the DAC output is routed to a transformer which defines the board as a DAC5682z EVM or routed to the TRF3703 which results in the TSW3082 EVM. Figure 1. DAC5682Z Resistor Jumper Configuration Figure 2.

  • Page 4: Vcxo

    The CDCM7005 requires a VCXO or external clock source to derive its output clock signals. The VCXO is at reference designator U6. This TSW3082 and DAC5682z EVM release does not have a VCXO and requires an external clock source on SMA J6. The VCXO can be changed to operate the Demo Kit with different clocking schemes for different modulation standards or for specific customer requirements.
