evaluation kit on a CD-ROM.
Signal Path Digital Interface hardware is available
through the National Semiconductor website (part
number: WAVEVSN 5.1).
3.0 Evaluation Kit Contents and Board
Assembly
The ADC14DS105KARB evaluation kit includes the
following items:
The ADC14DS105KARB is factory configured for
evaluation of input signals up to 35 MHz. Each board
is populated with an analog input network which has a
lowpass filter with a cutoff frequency of approximately
35 MHz.
The LMK02000, which provides the sample clock for
the ADC, must be programmed to correctly configure it
for the proper operating frequency.
microcontroller board (ADC14PIC REV. A) is used to
program the registers of the LMK02000 precision clock
conditioner chip.

Please note that the ADC14DS105KARB is only
compatible with National Semiconductor’s WaveVision
5.1 Digital Interface board.
4.2 Serial Programming Interface (SPI)
The
ADC14DS105 can be selected either through the SPI
or by direct pin control through the jumpers on the
evaluation board. The ADC14DS105KARB evaluation
board is delivered with the ADC14DS105 configured for
SPI operation.
The serial programming interface enable (SPI_EN) pin
jumper on the ADC14DS105KARB selects the state of
the SPI_EN pin. When the jumper is in place, the pin
state is asserted HIGH, the SPI is active and the direct
control pins have no effect. When the jumper is
removed, the SPI_EN state is LOW, the SPI is
deactivated and the ADC modes are pin-controlled
through the DLC, WAM, TEST jumpers. The SPI
interface is routed through the 60-pin HMZd connector
and is controlled through the WaveVision hardware and
software when the WaveVision 5.1 data capture
hardware is connected and active.
When the ADC14DS105KARB board is connected to
the WaveVision 5.1 board, the SPI software control
panel shown in Figure 3 will automatically appear. This
window should be used to set the modes of the
ADC14DS105 when the SPI is enabled. Please ensure
that the fields in the window correspond to Figure 3.
