CM2009 VGA Port Companion Circuit Features Product Description * The CM2009 connects between a video graphics controller embedded in a PC, graphics adapter card or set top box and the VGA or DVI-I port connector. The CM2009 incorporates ESD protection for all signals, level shifting for the DDC signals and buffering for the SYNC signals. ESD protection for the video, DDC and SYNC lines is implemented with low-capacitance current steering diodes. * * * * * * * Includes ESD protection, level-shifting, buffering and sync impedance matching 7 channels of ESD protection for all VGA port connector 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 maximum 5V drivers for HSYNC and VSYNC lines Integrated impedance matching resistors on sync lines Bi-directional level shifting N-channel FETs provided for DDC_CLK & DDC_DATA channels Backdrive protection on DDC lines Compact 16-lead QSOP package Applications * All ESD diodes are designed to safely handle the high current spikes specified by IEC-61000-4-2 Level 4 (8KV contact discharge if CBYP is present, 4KV if not). The ESD protection for the DDC signal pins are designed to prevent "back current" when the device is powered down while connected to a monitor that is powered up. Separate positive supply rails are provided for the VIDEO, DDC and SYNC channels to facilitate interfacing with low voltage video controller ICs to provide design flexibility in multi-supply-voltage environments.

These buffers accept TTL input levels and convert them to CMOS output levels that swing between Ground and VCC_SYNC, which is typically 5V. Additionally, each driver has a series termination resistor (RT) connected to the SYNC_OUT pin, eliminating the external termination resistors typically required for the HSYNC and VSYNC lines of the video cable. There are three versions with different values of RT to allow termination at typically 65 (CM2009-00) or 55 (CM2009-01) or 15 (CM2009-02). The 15 (CM2009-02) version will typically require two external resistors which can be chosen to exactly match the characteristic impedance of the SYNC lines of the video cable. Two N-channel MOSFETs provide the level shifting function required when the DDC controller is operated at a lower supply voltage than the monitor. The gate terminals for these MOSFETS (VCC_DDC) should be connected to the supply rail (typically 3.3V) that supplies power to the transceivers of the DDC controller.

BYP, VCC_VIDEO and VCC_SYNC must be bypassed to GND via a low impedance ground plane with a 0.2F, 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, VIDEO_3, SYNC_OUT1, SYNC_OUT2, DDC_OUT1 and DDC_OUT2. All other pins are ESD protected to the industry standard 2kV Human Body Model (MIL-STD-883, Method 3015). The bypass capacitor at the BYP pin may optionally be omitted, in which case the max. ESD withstand voltage for the DDC_OUT1 and DDC_OUT2 pins is reduced to 4kV. Note 4: This parameter is guaranteed by design and characterization. Note 5: The SYNC_OUT pins on the CM2009-02 are guaranteed for 2kV HBM ESD protection. (c) 2004 California Micro Devices Corp.

Typical Application Connection Diagram NOTES 1 The CM2009 should be placed as close to the VGA or DVI-I connector as possible. 2 The ESD protection channels VIDEO_1, VIDEO_2, VIDEO_3 may be used interchangeably between the R, G, B signals. 3 If differential video signal routing is used, the RED, BLUE, and GREEN signal lines should be terminated with external 37.5 resistors. 4 "VF" are external video filters for the RGB signals. 5 Supply bypass capacitors C1 and C2 must be placed immediately adjacent to the corresponding Vcc pins. Connections to the Vcc pins and ground plane must be made with minimal length copper traces (preferably less than 5mm) for best ESD protection. 6 The bypass capacitor for the BYP pin has been omitted in this diagram. This results in a reduction in the maximum ESD withstand voltage at the DDC_OUT pins from 8kV to 4kV. If 8kV ESD protection is required, a 0.2F ceramic bypass capacitor should be connected between BYP and ground. 7 The SYNC buffers may be used interchangeably between HSYNC and VSYNC. 8 The EMI filters at the SYNC_OUT and DDC_OUT pins (C5 to C12, and Ferrite Beads FB1 to FB4) are for reference only. The component values and filter configuration may be changed to suit the application. 9 The DDC level shifters DDC_IN, DDC_OUT, may be used interchangeably between DDCA_CLK and DDCA_DATA. 10 R1, R2 are optional. They may be used, if required, to pull the DDC_CLK and DDC_DATA lines to VCC_5V when no monitor is connected to the VGA connector. If used, it should be noted that "back current" may flow between the DDC pins and VCC_5V via these resistors when VCC_5V is powered down. 11 For optimal ESD performance with the CM2009-02, an additional clamp device (such as the CMD PACDN042) should be placed on HSYNC/VSYNC lines between the external matching resistor and the VGA connector.
