PACVGA200
VGA Port Companion Circuit
Product Description
The PACVGA200 incorporates seven channels of ESD protection
for all signal lines commonly found in a VGA port. ESD protection is
implemented with current steering diodes designed to safely handle
the high surge currents encountered with IEC ? 61000 ? 4 ? 2 Level ? 4
ESD Protection ( ? 8 kV contact discharge). When a channel is
subjected to an electrostatic discharge, the ESD current pulse is
diverted via the protection diodes into either the positive supply rail or
ground where it 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 ? supply ? voltage environments.
Two non ? inverting drivers provide buffering for the HSYNC and
VSYNC signals from the Video Controller IC (SYNC_IN1,
SYNC_IN2). These buffers accept TTL input levels and convert them
to CMOS output levels that swing between Ground and V CC 4.
These drivers have nominal 60 W output impedance (R S ) 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 voltage than the monitor. Three 75 W
termination resistors suitable for terminating the video signals from
the video DAC are also provided. These resistors have separate 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 V CC 4 supply. When the PWR_UP input is LOW, the SYNC
outputs are driven LOW.
An internal diode (D1 in schematic on previous page) is also
provided so that V CC 3 can be derived from V CC 4, if desired, by
connecting V CC 3 to V_BIAS. In applications where V CC 4 may be
powered down, diode D1 blocks any DC current paths from the
DDC_OUT pins back to the powered down V CC 4 rail via the top ESD
protection diodes.
