- 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 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 15
to over 100.
The CM2010 is supplied in a 10-lead MSOP package
and is available with optional lead-free finishing.

the VGA controller device and the video connector.
4
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.
5
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.
6
GND
Ground reference supply pin.
7
SYNC_IN1
Sync signal buffer input. Connects to the VGA controller side of one of the sync lines.
8
SYNC_OUT1
Sync signal buffer output. Connects to the video connector side of one of the sync lines.
9
SYNC_IN2
Sync signal buffer input. Connects to the VGA controller side of one of the sync lines.
10

PRELIMINARY
Specifications
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, V
CC
must be bypassed to
GND via a low impedance ground plane with a 0.22
F, 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.
