DESCRIPTION
The UTC CCVGA7C9 is an ESD solution for the VGA or DVI-I
port connector. This device integrates 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.
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
65(UTC CCVGA7C900) or 15(UTC CCVGA7C902).
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 the MOSFETs (VCC_DDC) should be connected to the
supply rail (typically 3.3 V) that supplies power to the transceivers of the DDC controller.
All ESD diodes are designed to safely handle the high current spikes specified by IEC-61000-4-2 Level 4 (±8kV
contact discharge if CBYP is 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.
FEATURES
* 7 Channels of ESD protection for all VGA port connector pins
meeting IEC-61000-4-2 Level 4 ESD requirements (±8kV
contact discharge)
* Includes ESD protection, level-shifting, buffering and sync
impedance matching
* Very low loading capacitance from ESD protection diodes on
VIDEO lines (4pF maximum)
