MAX100 Evaluation Kit
_______________General Description
The MAX100 evaluation kit (EV kit) allows high-speed
digitizing of analog signals at 250Msps, using the
MAX100 ADC. All circuitry required to support the ADC
is supplied. Data output is available in three formats:
divide-by-1, divide-by-2, or divide-by-5 mode.
Clocking is provided by an external clock source input
through an SMA connector.
The MAX100 EV kit main board comes complete with a
MAX100 high-speed, 8-bit flash ADC with strobed com-
parators, latched outputs, and an internal track/hold.
Analog input to the board is through two SMA coaxial
connectors, for use with either differential or single-
ended inputs.
Signals from the main board include dual-output data
paths that allow easy interfacing to external circuitry.
These two outputs can be configured either to provide
two identical fast outputs (A and B), or an 8-to-16
demultiplexer mode that reduces the output data rates
to one-half the sample clock rate. This demux is inter-
nal to the MAX100 ADC and is one of the key features
of this device.
A termination board with 50鈩?ECL pull-down resistors is
also supplied, and is connected to the main board with a
3x32 pin EURO-card connector. It provides access to the
converter output data and provides proper ECL data ter-
mination. In addition to the pull-down resistors, this board
has two ranks of square pins, each providing eight differ-
ential data outputs plus clock outputs. Either AData or
BData may be observed with a high-speed logic analyzer.
Standard power supplies of +5V and -5.2V are needed
to operate the MAX100 EV kit board. Power can be
supplied through the 3x32 EURO-card connector or
through the pads on the edge of the board. Nominal
power dissipation for both boards is 12W. The board
set comes fully assembled and tested, with the
MAX100 installed.
