CM2006

www.DataSheet4U.com PRELIMINARY CM2006 VGA Port Companion Circuit For Monitors Features Includes ESD protection, level-shifting, buffering and sync impedance matching VESA VSIS Version 1 Revision 2 Compatible Interface Supports Optional NAVI Signalling requirements 7 channels of ESD protection for all VGA port connector pins meeting IEC-61000-4-2 Level 4 ESD requirements (±8kV contact discharge) Very low loading capacitance from ESD protection diodes on VIDEO lines, 3pF maximum Schmitt triggered input buffers for HSYNC and VSYNC lines Bi-directional level shifting N-channel FETs provided for DDC_CLK & DDC_DATA channels Backdrive protection on all lines Compact 16-lead QSOP package Product 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 (±8kV contact discharge). The ESD protection for the DDC, SYNC and VIDEO signal pins is designed to prevent "back 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...
