CM2010
VGA Port Protection with Integrated Sync Buffers
Features
Product Description
•
The CM2010 connects between a video graphics controller, embedded in a PC or in a graphics adapter
card, and the VGA port connector. The CM2010 integrates ESD protection for 3 VGA output signals implemented with low-capacitance current steering diodes
such that an ESD pulse is diverted into either the positive supply rail or ground, where it may be safely dissipated.

3 channels of ESD protection for RGB output pins
meeting IEC-61000-4-2 Level 4 ESD requirements
(8kV contact discharge)
Very low loading capacitance from ESD protection
diodes on VIDEO lines, 4pF typical
3.3/5V 24mA buffer drivers for HSYNC and
VSYNC lines
VESA Video Signal Standard (VSIS) - Version 1,
Rev. 2 Compatible Outputs
Compact 10-lead MSOP package
Lead-free version available
Two 24mA non-inverting drivers provide buffering for
the HSYNC and VSYNC signals from the video controller IC (SYNC1, SYNC2). These buffers accept low voltage 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.
Applications
•
All ESD diodes are designed to safely handle the high
current spikes specified by IEC61000-4-2 Level 4 ESD
(8kV contact discharge).
VGA and DVI-I ports in:
- Desktop and Notebook PCs
- Graphics Cards
- Set Top Boxes
The CM2010 is supplied in a 10-lead MSOP package
and is available with optional lead-free finishing.

Note 1: All parameters specified over standard operating conditions unless otherwise noted.
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. Applicable 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.
