SHORT PRODUCT APPLICATION NOTE
The SWVGA-200 incorporates 7 channels of ESD protection for signal lines commonly found in a VGA port . ESD protection is implemented with current steering diodes designed to safely handle the high peak surge currents associated with the IEC-1000-4-2 Level-4 ESD Protection Standard (8KV contact discharge). When a channel is subjected to an electrostatic discharge, the ESD current pulse is diverted via the protection diodes into the positive supply rails or ground where they may be safely dissipated. Separate positive supply rails are provided for the VIDEO,DDC and SYNC channels to facilitate interfacing with low voltage Video Controller ICs and provide design flexibility in multi-suply-voltage environments. Two non-inverting drivers provide buffering for the HSYNC and VSYNC channels 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 VCC4.These drivers have nominal 60W otput impedance to match the characteristic impedance of the HSYNC&VSYNC lines of the video cables typically used in PC applications. Two N-channel FETs provide the level shifting function required when the DDC controller is operated at a lower supply voltae than the monitor. Three 75W termination resistors suitable for terminating the video signals from the video DAC are also provided. Thee resistors have separated input pins to allow insertion of additional EMI filtering, if required, between the termination point and the ESD protection diodes. These resistors are matched to better than 2% for excellent signal level matching for the R/G/B signals. When the PWR_UP input is driven LOW the SYNC inputs can be floated without causing the SYNC buffers to draw any current from the VCC3 supply. When the PWR_UP input is LOW the SYNC outputs are driven LOW. An internal diode (D1 in schematic below) is also provided so that VCC4 can be derived from VCC4, if desired, by connecting VCC3 to V_BIAS. In applications where VCC4 may be powered down, diode D1 blocks any DC current path from the DDC_OUT pins back to the powered down VCC4 rail via the top ESD protection diodes.
SEMICONDUCTOR-THIN FILM MANUFACTURING PROCESS DESCRIPTION
Integrated passive networks are manufactured using advanced thin film technologies including ultra -stable and self passivating Tantalum Nitride resistors, gold interconnect metallization and reliable MNOS capacitors to achieve excellent uniformity, performance and reliability. Thin film resistor technology is the preferred solution for all applications that require low noise, long term stability and excellent performance at very high frequencies. Semiconwell employs proprietary thin film technologies for deposition of a wide range of sheet resistance films from 1W/sq to 10,000 W/sq. All Semiconwell's products are available in die form and as KGD, known good die and are ideal for high reliability hybrid and multi chip module applications. Besides thin film resistors, Semiconwell integrates capacitors, Schottky diodes, Zener diodes and transistors. Integrated passive and active networks are manufactured using Semiconwell's in house high reliability semiconductor manufacturing processes. All semiconductor devices employ precision doping via ion implantation, silicon nitride junction passivation, platinum silicided contacts and gold interconnect metallization for best performance and reliability. MNOS capacitors and Tantalum Nitride resistors are easily integrated with Schottky diodes to provide complete standard and custom RCD solutions. In die form, these products are ideal for hybrid and multi chip module applications. In packaged form, these products are the best solution where space and weight are a concern.
