DIGITAL INPUTS

Digital inputs on the AD9984A (HSYNC0, HSYNC1, VSYNC0,

VSYNC1, SOGIN0, SOGIN1, SDA, SCL, and CLAMP) are

designed to work with 3.3 V signals, but are tolerant of 5 V

signals. Therefore, no extra components need to be added if

using 5 V logic.

Any noise that gets onto the Hsync input trace adds jitter to the

system. Therefore, minimize the trace length and do not run

any digital or other high frequency traces near it.

Reference Bypass

The AD9984A has two reference voltages that must be bypassed

for proper operation of the ADC. REFLO and REFHI are

connected to each other through a 10 μF capacitor. These

references are used by the ADC circuitry to assure the greatest

stability. Place them as close to the AD9984A pin as possible.
