THEORY OF OPERATION
The ADA4417-3 is a low cost, integrated video filtering and
driving solution that offers a 38 MHz, 1 dB bandwidth to meet
the requirements of high definition video. Each of the three
filters has a sixth-order Butterworth response that includes
group delay equalization. Group delay variation from 1 MHz to
36 MHz is only 5 ns, resulting in greater stop-band attenuation
and minimal phase distortion.
The ADA4417-3 is designed to operate in many video
environments. With a supply range of 3.3 V to 5 V, it requires
a relatively low nominal quiescent current of 10 mA per
channel. This makes the ADA4417-3 well suited for portable
high definition video applications. Additionally, for other low
power applications, the part can be powered down to draw
typically 10 μA by pulling the DISABLE pin to ground. The
ADA4417-3 is also well suited for high encoding frequency
applications because it maintains a stop-band attenuation of over
40 dB out to 500 MHz. Typical power supply rejection ratio
(PSRR) is greater than 70 dB, providing excellent rejection in
systems with supplies that are noisy or underregulated.
The ADA4417-3 is intended to accept dc-coupled inputs
from an encoder or other ground-referenced video signals.
The ADA4417-3 inputs are high impedance. No minimum or
maximum input termination is required; however, terminations
above 1 kΩ may degrade crosstalk performance at high
frequencies.
Each filter input includes level-shifting circuitry. The level-
shifting circuitry adds a dc component of 100 mV to ground-
referenced input signals so that they reproduce accurately,
without the output buffers hitting the ground rail. For lowest
off state power consumption when using the dc offset function,
it is recommended that the DCO and DISABLE pins be tied
together.
The output drivers on the ADA4417-3 have rail-to-rail output
capabilities with 6 dB gain. Each output is capable of driving
two ac- or dc-coupled, 75 Ω source-terminated loads. If a large
dc output level is required while driving two loads, ac coupling
should be used to limit the power dissipation.
