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 V
CC_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 (R
T
) 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.

Note 3: Per the IEC-61000-4-2 International ESD Standard, Level 4 contact discharge method. BYP, V
CC
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.
