CM2006
Description
The CM2006 connects between the VGA or DVI- I port connector and the internal analog or digital flat panel controller logic. The CM2006 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 connector interface pins are designed to safely handle the high current spikes specified by IEC- 61000- 4- 2 Level 4 (±8 k V contact discharge). The ESD protection for the DDC, SYNC and VIDEO signal pins is designed to prevent “backdrive current” when the device is powered down while connected to a video source that is powered up.
Separate positive supply rails are provided for the VIDEO / SYNC signals and DDC signals to facilitate interfacing with low voltage video controller ICs and microcontrollers to provide design flexibility in multi- supply- voltage environments.
