    Through the use of JP7, the user can select the I/O voltage to be either 1.8V or 3.3V. If the EB-GS2972 and the EB-GS2970 are connected together, one supply will power both boards. Therefore, the +5V DC power is only required on either the EB-GS2972 or the EB-GS2970.
  • Page 6 When DETECT_TRS is LOW, the device extracts all internal timing from the supplied H:V:F or CEA-861 timing signals, dependent on the status of the TIM861 pin. When DETECT_TRS is HIGH, the device extracts all internal timing from TRS signals embedded in the supplied video stream. EB-GS2972 6 of 22 Evaluation Board User Guide...

    GS2972s GSPI pins. To communicate with the GS2972 and the two SRCs, a Gennum USB to GSPI dongle must be connected to the GSPI header. A GSPI dongle is provided for communication to the GSPI interface. If you have the EB-GS2972 and the EB-GS2970 connected together, only one GSPI dongle is required, and can be connected to either of the boards.
