HDR-60 Base Board – Revision B
Initial Setup and Handling
The following is recommended reading prior to removing the evaluation board from the static shielding bag and
may or may not apply to your particular use of the board.
CAUTION: The devices on the board can be damaged by improper handling.
The devices on the evaluation board contain fairly robust ESD (Electro Static Discharge) protection structures
within them, able to withstand typical static discharges (see the “Human Body Model” specification for an example
of ESD characterization requirements). Even so, the devices are static sensitive to conditions that exceed their
designed in protection. For example: higher static voltages, as well as lower voltages with lower series resistance
or larger capacitance than the respective ESD specifications can potentially damage or degrade the devices on the
evaluation board.
As such, it is recommended that you wear an approved and functioning grounded wrist strap at all times while han-
dling the evaluation board when it is removed from the static shielding bag. If you will not be using the board for a
while, it is best to put it back in the static shielding bag. Please save the static shielding bag and packing box for
future storage of the board when it is not in use.
When reaching for the board, it is recommended that you first touch the ground plane of the board (for example, the
metal shielding of the HDMI connector). This will neutralize any static voltage difference between your body and the
board prior to any contact with signal I/O.
CAUTION: To minimize the possibility of ESD damage, the first and last electrical connections to the board should
always be from test equipment chassis ground to the ground plane of the board.
Before connecting signals or power to the board, attach a cable from chassis ground on grounded test equipment
to the ground plane of the board. Connecting the board ground to test equipment chassis ground will decrease the
risk of ESD damage to the I/O on the board as the initial connections to the board are made. Likewise, when
unplugging cables from the evaluation board, the last connection unplugged, should be the chassis GND connec-
tion to the evaluation board GND. If you have a signal source that is floating with respect to chassis GND, attempt
to neutralize any static charge on that signal source prior to attaching it to the evaluation board.
If you are holding or carrying the board when it is not in a static shielding bag, please keep one finger on the ground
plane of the board, for example the metal shielding of the HDMI connector. This will keep the board at the same
voltage potential as your body until you can pick up the static shielding bag and put the board back in it.
Electrical, Mechanical, and Environmental Specifications
The nominal board dimensions are 203.2 mm x 42 mm (8.000” x 1.654”). Additional mechanical board dimension
information is included on the mechanical drawing shown in Appendix A, Figure 24. On the physical board itself,
connectors include pin 1 indictors as either an arrow, or triangle point near pin 1 on the outer layer silk screen. The
environmental specifications are as follows:
• Operating temperature: 0 °C to 55 °C
• Storage temperature: -40 °C to 75 °C
• Humidity: <95% without condensation
• 11 V to 18 V DC (20 watts max.)
