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. All ESD diodes are designed to safely handle the high current spikes specified by IEC-61000-4-2 Level 4 (±8KV contact discharge if CBYPis 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. Two non-inverting drivers provide buffering for the HSYNC and VSYNC signals from the video controller IC (SYNC1,SYNC2). 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 65Ω (CM2009-00) or 15Ω (CM2009-02). The 15Ω(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

The CM3202-00 is a dual-output low noise linear regulator designed to meet SSTL-2 and SSTL-3 specifications for DDR-SDRAM VDDQ supply and termination voltage VTTsupply. With integrated power MOSFET's, the CM3202-00 can source up to 2A of VDDQcontinuous current, and source or sink up to 2A VTT continuous current. The typical dropout voltage for VDDQ is 500mV at 2A load current. The CM3202-00 provides fast response to transient load changes. Load regulation is excellent, from no load to full load. It also has built-in over-current limits and thermal shutdown at 170°C. The CM3202-00 supports Suspend-To-RAM (STR) and ACPI compliance with shutdown mode which tri-states VTT to minimize quiescent system current. The CM3202-00 is packaged in an easy-to-use TDFN-8. Low thermal resistance allows it to withstand high power dissipation at 85°C ambient. It operates over the industrial ambient temperature range of -40°C to 85°C.
