CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the ADV7128 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.

Stresses above those listed under “Absolute Maximum Ratings” may cause
permanent damage to the device. This is a stress rating only and functional
operation of the device at these or any other conditions above those listed in the
operational sections of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
Analog Output Short Circuit to any Power Supply or Common can be of an

Function
Clock input (TTL compatible). The rising edge of CLOCK latches the R0–R9, G0–G9, B0–B9, SYNC and
BLANK pixel and control inputs. It is typically the pixel clock rate of the video system. CLOCK should be driven
by a dedicated TTL buffer.
Data inputs (TTL compatible). Data is latched on the rising edge of CLOCK. D0 is the least significant data bit.
Unused data inputs should be connected to either the regular PCB power or ground plane.
Current output. This high impedance current source is capable of directly driving a doubly terminated 75
coaxial cable.

Compensation pin. This is a compensation pin for the internal reference amplifier. A 0.1 F ceramic capacitor
must be connected between COMP and V
Voltage reference input. An external 1.23 V voltage reference must be connected to this pin. The use of an exter-
nal resistor divider network is not recommended. A 0.1 F decoupling ceramic capacitor should be connected be-
