Applications
VGA and DVI-I ports in: - Desktop and Notebook PCs - Graphics Cards - Set Top Boxes Product Description The CM2010 connects between a video graphics con- troller, embedded in a PC or in a graphics adapter card, and the VGA port connector. The CM2010 inte- grates ESD protection for 3 VGA output signals imple- mented with low-capacitance current steering diodes such that an ESD pulse is diverted into either the posi- tive supply rail or ground, where it may be safely dissi- pated. All ESD diodes are designed to safely handle the high current spikes specified by IEC61000-4-2 Level 4 ESD (8kV contact discharge). Two 24mA non-inverting drivers provide buffering for the HSYNC and VSYNC signals from the video control- ler IC (SYNC1, SYNC2). These buffers accept low volt- age input levels and convert them to CMOS output levels that swing between Ground and VCC_SYNC, which is typically 5V for Legacy VESA compatibility, but can be operated at 3.3V. Additionally, the output impedance of the drivers can be discretely adjusted via external series termination resistors (RT) for maximum flexibility. The output impedance of the drivers can be adjusted over a wide range from 15Ω to over 100Ω. The CM2010 is supplied in a 10-lead MSOP package and is available with optional lead-free finishing.

DESCRIPTION
VCC_SYNC This is an isolated supply input for the SYNC_1 and SYNC_2 level shifters and their associ- ated ESD protection circuits. VCC_VIDEO This is a supply pin specifically for the VIDEO_1, VIDEO_2 and VIDEO_3 ESD protection cir- cuits. VIDEO_1 Video signal ESD protection channel. This pin is typically tied one of the video lines between the VGA controller device and the video connector. VIDEO_2 Video signal ESD protection channel. This pin is typically tied one of the video lines between the VGA controller device and the video connector. VIDEO_3 Video signal ESD protection channel. This pin is typically tied one of the video lines between the VGA controller device and the video connector. GND Ground reference supply pin. SYNC_IN1 Sync signal buffer input. Connects to the VGA controller side of one of the sync lines. SYNC_OUT1 Sync signal buffer output. Connects to the video connector side of one of the sync lines. SYNC_IN2 Sync signal buffer input. Connects to the VGA controller side of one of the sync lines. SYNC_OUT2 Sync signal buffer output. Connects to the video connector side of one of the sync lines.

Note 2: These parameters apply only to the SYNC drivers. Note 3: Per the IEC-61000-4-2 International ESD Standard, Level 4 contact discharge method. BYP, VCC must be bypassed to GND via a low impedance ground plane with a 0.22µF, low inductance, chip ceramic capacitor at each supply pin. ESD pulse is applied between the applicable pins and GND. ESD pulses can be positive or negative with respect to GND. Appli- cable pins are: VIDEO_1, VIDEO_2 and VIDEO_3. All other pins are ESD protected to the industry standard ±2kV Human Body Model (MIL-STD-883, Method 3015). Note 4: This parameter is guaranteed by design and characterization. Note 5: Rise and fall times measured between 0.5V and 2.4V.
