- DUT On vs. DUT Off Many HDMI CTS tests require a power off condition o n the System Under Test. Many Dual Rail Clamp (DRC) ESD diode configurations will be forward biased whe n their VDD rail is lower than the I/O pin bias, thereby exhibiting extremely high apparent capacitance meas urements, for example. The MediaGuard backdrive isolation circuitry limits this current to less than 10 A, and will help ensure HDMI compliance. 2. EEPROM Configurations The EDID EEPROM may be connected to either the ASIC LV domain or Connector 5V domain of the CM2021. See the MediaGuard EEPROM Application Note for furt her circuit connection and layout examples.
