MAX9680

Application Information
Input Considerations
The MAX9680 input is DC-coupled. When the supply volt-
age is between 2.7V and 3.6V, the input voltage range
extends from ground to 0.445V. When the supply volt-
age is between 2.8V and 3.6V, the input voltage range
extends from ground to 0.464V. A typical current-output
DAC that operates from a single supply usually creates
a composite video signal with a sync tip very close to
ground. Hence, the DAC output can be directly con-
nected to the MAX9680 input. Keep the board trace as
short as possible to minimize parasitic stray capacitance
and prevent unintentional high-frequency attenuation.
Output Considerations
The MAX9680 output must be DC-coupled. No
AC-coupled capacitors are allowed. The MAX9680 con-
nects directly to the video cable through a 75I series
back-termination resistor. The other end of the cable
should be properly terminated with a 75I resistor as
well. Because of this configuration, the peak-to-peak
amplitude as well as the DC level of the signal is divided
by two. The MAX9680 output signal is level-shifted up so
the sync tip is approximately 120mV.
Power-Supply Bypassing and Ground
The MAX9680 operates from a single-supply voltage
down to 2.7V, allowing for low-power operation. Bypass
VDD to GND with a 0.1FF capacitor. Place all external
components as close as possible to the device.
