Features - - - - - - 3 channels of ESD protection for RGB output pins meeting IEC-61000-4-2 Level 4 ESD requirements (8k V contact discharge) Very low loading capacitance from ESD protection diodes on VIDEO lines, 4p F typical 3.3/5V 24m A buffer drivers for HSYNC and VSYNC lines VESA Video Signal Standard (VSIS) - Version 1, Rev. 2 patible Outputs pact 10-lead MSOP package Lead-free version available 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. All ESD diodes are designed to safely handle the high current spikes specified by IEC61000-4-2 Level 4 ESD (8k V contact discharge). Two 24m A 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 patibility, 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.
