CM2009 VGA Port Companion Circuit Product Description The CM2009 connects between a video graphics controller embedded in a PC, graphics adapter card or set top box and the VGA or DVI−I port connector. The CM2009 incorporates ESD protection for all signals, level shifting for the DDC signals and buffering for the SYNC signals. ESD protection for the video, DDC and SYNC lines is implemented with low−capacitance current steering diodes. All ESD diodes are designed to safely handle the high current spikes specified by IEC−61000−4−2 Level 4 (±8 kV contact discharge if CBYP is present, ±4 kV if not). The ESD protection for the DDC signal pins are designed to prevent “back current” when the device is powered down while connected to a monitor that is powered up.
