CM2010

VGA Port Protection with Integrated Sync Buffers

Features

Product Description

•

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

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).

•

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 control-

ler IC (SYNC1, SYNC2). These buffers accept low volt-

age input levels and convert them to CMOS output

Applications

•

VGA and DVI-I ports in:

- Desktop and Notebook PCs

- Graphics Cards

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

- Set Top Boxes

external series termination resistors (R ) 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.
