Applications
Monitors Video graphics controllers embedded in PCs Graphics adapter cards Set-top boxes Product Description The CM2009-05CP connects between the VGA or DVI-I port connector and the internal analog or digital flat panel controller logic. It can also be used for source devices such as a set-top box. The CM2009- 05CP 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 connector interface pins are designed to safely handle the high current spikes specified by IEC- 61000-4-2 Level 4 ( ±8kV contact discharge). The ESD protection for the DDC, SYNC and VIDEO signal pins is designed to prevent "back current" when the device is powered down while connected to a video source or a video sink that is powered up. Positive supply rails are provided for the VIDEO / SYNC signals and DDC si gnals to facilitate interfacing with low voltage video controller ICs and microcontrollers to provide design flexibility in multi- supply-voltage environments. Two Schmitt-triggered non-inverting buffers redrive and condition the HSYNC and VSYNC signals from the video connector (SYNC1, SYNC2). These buffers accept VESA VSIS compliant TTL input signals and convert them to CMOS output levels that swing between ground and V CC. Two N-channel MOSFETs provide the level shifting function required when the DDC controller or EDID EEPROM is operated at a lower supply voltage than the monitor. The gate terminals for these MOSFETS should be connected to the supply rail (typically 3.3V, 2.5V etc.) that supplies power to the transceivers of the DDC controller.
