VGA PORT COMPANION CIRCUIT
PACVGA201
VGA Port Companion Circuit
Product Description
The PACVGA201 provides seven channels of ESD protection for
all signal lines commonly found in a VGA port. ESD protection is
implemented with currentïsteering diodes designed to safely handle
the high surge currents encountered with IECï61000ï4ï2 Levelï4
ESD Protection (r8 kV 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 rail or
ground where it may be safely dissipated.
Separate positive supply rails are provided for the VIDEO,
DDC_OUT and SYNC channels to facilitate interfacing with
lowïvoltage video controller ICs and to provide design flexibility in
multipleïsupplyïvoltage environments.
An internal diode (D1, in schematic below) is provided such that
VCC2 is derived from VCC3 (VCC2 does not require an external power
supply input). In applications where VCC3 may be powered down,
diode D1 blocks any DC current path from the DDC_OUT pins back to
the powered down VCC3 rail via the upper ESD protection diodes.
Two nonïinverting 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 VCC3.
When the PWR_UP input is driven LOW, the SYNC outputs are
driven LOW and the SYNC inputs can float: no current will be drawn
from the VCC3 supply.
The PACVGA201 is housed in a 16ïpin QSOP package with RoHS
compliant leadïfree finishing.
