GENERAL DESCRIPTION
The ADIS16250/PCB, ADIS16251/PCB, and ADIS16255/PCB
are simple evaluation boards that provide convenient access to
the ADIS16250, ADIS16251, ADIS16255 using a standard
2 mm, 2 × 6, connector interface. These connectors can be
accessed using a variety of cable options, including standard
1 mm ribbon cables. The ADIS1625x/PCB is designed to be
evaluated in an existing digital platform (such as MCU, DSP,
FPGA, PLD) or as part of the ADISEVAL system. Four
mounting holes (sized for 2-56 or 2 mm screws) have been
provided to secure the board during evaluation.
CIRCUIT DESCRIPTION
The schematic, layout, and parts list for the ADIS1625x/PCB
can be found in
Figure 1, Figure 2, and Table 1.
The ADIS1625x’s digitized outputs can be accessed using the
4-wire serial port interface (SPI) signals on J1: SCLK, CS, DOUT,
and DIN. For specific information on using the ADIS1625x SPI
interface, refer to the
ADIS16250 data sheet. Auxiliary functions,
such as the 12-bit ADC input, can be accessed using J2. C1
provides additional power supply filtering but is generally not
required. C2 provides pads for installing a capacitor to reduce
the ADIS1625x’s bandwidth.

SPECIAL NOTES ON HANDLING
Note that the ADIS1625x/PCB is not reverse-polarity protected.
Reversing the power supply or applying inappropriate voltages
(that is, voltages outside the Absolute Maximum Ratings in the
ADIS16250 data sheet) to any pin may damage the ADIS1625x/PCB.
