1.0 Introduction
The ADC14DS105KARB is a near-zero IF receiver
reference design board that utilizes the following
components from National Semiconductor:
2.0 Data Capture
The digital data from the ADC14DS105KARB reference
design board can be captured with a suitable
instrument, such as a logic analyzer, or with National
Semiconductor’s
acquisition hardware and software platform.
ADC14DS105KARB board can be connected to the
data acquisition hardware through the 60-pin connector
mounted on the board edge.

This subsystem reference design utilizes the LMH6552
current feedback amplifier as a differential driver for the
ADC14DS105. The sampling clock is provided by a
100 MHz VCXO which is locked to a reference
oscillator by the LMK02000.
The 1 GHz input bandwidth of the ADC and the 1.5
GHz differential amplifier gain stage provide excellent
performance in this application.

WiMAX and WCDMA receiver systems.
The ADC14DS105KARB is compatible with National
Semiconductor’s WaveVision 5.1 Signal Path Digital
Interface Board and associated WaveVision software.
Please note that the ADC14DS105KARB board is not
compatible with previous versions of the WaveVision
hardware (WaveVision 4.x Digital Interface Boards).
The WaveVision hardware and software package
allows fast and easy data acquisition and analysis. The
WaveVision hardware connects to a host PC via a USB
cable and is fully configured and controlled by the latest
