Evaluation Platform Overview

Intersil’s high-speed ADC evaluation platform consists of

custom designed hardware and software. The function of

the hardware is to provide power to the ADC and to

excite and/or measure the appropriate analog and digital

inputs and outputs. The software is required to configure

the device for initial operation, to modify the device

functionality or parameters, and to process and display

the output data.

Two versions of the software are provided to support two

different ADC families: version 1.15.6c supports all

KAD27XX and KAD5XXX devices, while version 1.20c

supports the ISLA11XP50 family. Refer to the Konverter

Installation Guide (AN1434) for details on installing and

running the different versions.

Hardware

There are two components in the hardware portion of the

evaluation platform: the daughter card and the

motherboard (Figure 1). The ADC is contained on the

daughter card, which routes power from the

motherboard and contains the analog input circuitry,

clock drive and decoupling. The daughter card interfaces

to the motherboard through a mezzanine connector. The

motherboard contains a USB interface, an FPGA and

SRAM. The motherboard serves as the interface between

the host PC and the ADC daughter card. Most of the ADC

functionality is controlled by the motherboard, although

some daughter cards have jumpers to set certain

operating modes. The FPGA accepts output data from the

ADC and buffers it in the SRAMs before passing it to the

PC at a lower speed for post-processing. The maximum

buffer depth is approximately one million words.

The user must supply low-jitter RF generators for the

clock and analog inputs. Recommendations of suitable

generators can be found in Appendix A.

Many low-jitter RF generators exhibit high harmonic

spectral content relative to the ADC performance. A

band-pass filter is recommended to attenuate the

harmonics. A wideband attenuator in series with the

band-pass filter is also recommended for daughter cards

without on-board attenuators. Current spikes from the

ADC’s switched capacitor sample-and-hold amplifier can

create signal reflections in the coaxial cable. The

attenuator reduces these reflections and improves

performance.
