VP1058
APPLICATION NOTES
As with all high speed analog-to-digital converters, careful
consideration must be given to circuit layout. The best
performance from the VP1058 can be achieved by use of
separate analog and digital ground planes. Ideally these
should be connected at a point close to the device. This will
reduce the amount of digital switching noise fed back into the
analog section of the converter, so aiding device performance.
Supply line decoupling is important when dealing with
mixed analog and digital signals, as they can provide a
feedback path from the digital output currents. Therefore, the
VP1058 should be decoupled close to the device supply pins
with good quality high frequency, low inductance capacitors.
Due to the high clock rates, long clock lines to the device
should be avoided to reduce noise pick up.
A typical applications circuit is shown below. The analog
input amplifier should be a wideband, high slew rate op-amp
used to drive the input directly. A stable reference is needed
for both input offset and gain control (e.g. REF12Z micropower
voltage reference as shown in Fig.6). Both analog input pins
should be connected close to the device with the input
amplifiers feedback loop closed at the point. The reference
inputs should be adequately decoupled to ground so as to limit
the effects of system noise on conversion accuracy. A
capacitor at the mid-reference point (as shown) may be useful
in correcting any inherent reference ladder skew.
The circuit will accept a 1V p-p video signal and level shift
and multiply it to provide the recommended 2V p-p signal to
drive the VP1058.
