should further be improved by using a 47mF tantalum

capacitor in parallel with a 100nF ceramic capacitor. If VCCA

is derived from VCCD, a small inductor should be used to

reduce digital noise on the analog power supply. Jitter and

noise on clock input pins must be minimised. Long clock

lines should therefore be avoided and all clock lines correctly

terminated. Cross talk of digital signals to the analog inputs

must also be prevented as sampling cross talk produces DC

offsets on the sampled data, for this reason analog inputs

should not be run next to clock or data lines. Device

connections to the ground plane should be as short as

possible.

Layout And Grounding

As with all high speed A to D converters, careful

consideration must be given to the PCB layout. High

performance can be obtained from the VP211 by tying all

grounds to a solid low impedance ground plane. Separate

analog and digital ground planes with a single common link

under the device can also be used to help reduce the

amount of digital noise fed back into the analog section of the

converter.

The VP211 should be decoupled with low impedance

100nF ceramic capacitors close to the package pins to avoid

lead inductance effects and the decoupling on supply lines

Application Circuit

A ripple voltage £ 10mV is recommended for good

system performance, e.g. If the analog input frequency F_in=

Fig.5 shows a typical applications circuit for the VP211.

The supply connections are made using separate low noise

digital and analog power supplies and VCCD is further

isolated from VCCO using a 1.2mH inductor.

The COMPA and COMPB pins must be decoupled to

reduce any ripple at low frequencies which may distort the

ADC driver ampliﬁer output, (see Fig.2.) The decoupling

capacitor value is determined by the required low frequency

performance of the system and can be obtained from the

following equation.

10KHz a value of 0.75mF is required for C_Comp

To ensure effective A.C. coupling at low input

frequencies, the coupling capacitors on pins 6 and 11 can be

calculated from the high pass ﬁlter corner frequency
