MODEL EB-L & EB-J ANALOG
SURFACE MOUNT ACCELEROMETER TEST SET•••••••

Easily test SDI’s analog surface mount accelerometers during concept
design or prior to installation
Chips can be removed and remain unharmed
Fully assembled for immediate implementation
Compatible with SDI Models, 1521,1522, 1525 and 1531
Use with the SDI Model 3330 or 3340 G-Loggers for quick calibration
Configurations available for SDI’s JLCC or LCC chip packages
Contents include:o One test board with L or J package zero-insertion force test
socket and compatible jumpers installedo One Ribbon cable with 10-pin connector

The Model EB-L Analog and EB-J Analog Test Sets provide a convenient means of testing and evaluating
SDI Models 1521, 1522, 1525, and 1531 surface mount accelerometers in either the LCC or JLCC package
format. The zero-insertion-force socket is pre-fitted to the board, which includes set jumpers for advanced
features of SDI accelerometers. A 10-pin connector and ribbon cable is provides connections to the user's
test equipment. The EB-L Set, EB-J Set, and SDI Surface Mount Accelerometers are each sold separately.

OPERATION
The EB-J and EB-L Analog Test Sets come fully assembled and ready to integrate with a test system.
1.
2.

Install the accelerometer into the socket with pin 1 ( ) towards the socket hinge.
With the 10-pin connector on the left (see board layout below) jumper pins are 1-2-3
a. EB-L Analog has 2 pin jumpers for both JP4 and JP5.
b. EB-J Analog has a 2-pin jumper for only JP4. There is no JP5 on this board

Please see specific, 1521, 1522, 1525, and 1531 accelerometer data sheets for a complete description of functions.

ADDITIONAL NOTES: EB-L ANALOG JUMPER USE
1.

Slave mode, SDI 1521, 1522, and 1531 accelerometers may be configured to run from an external CLK, to keepthem synchronized with other external components. JP 1 set to 1-2 turns off both the internal clock andtemperature output signal.

2.

Master mode. Alternative option in a multiple axis configuration is to configure one of the accelerometers toprovide a clock to the other Slave accelerometers (and external components if desired). JP 2 set to 1-2 turns on
the CLK OUT from the designated Master accelerometer.

3.

If JP 3 is installed, VR draws power from VDD. Similarly, with JP 5 installed the 2.5 volt is also derived from VR.
Remove JP 3 to provide external 5 volts to VR at pin 4 and JP 5 to provide external 2.5 volts at pin 9.

4.

The 1521, 1522, and 1531 have a temp signal output capability when in default mode or Master mode. The voltage
is approximately 1 - 1.3 volts at room temperature. Set JP 4 to 1-2. When the SDI 1521, 1522, and 1531 are inSlave mode (see note 1 above) the temperature output signal is disabled. Omitting JP 4 completely removes theresistor used in the temperature circuit or the recommended pull up line for 1510. A CLK may then be provided atPIN 3 to the accelerometer.

The EB-J Analog is not compatible with SDI 1527, contact SDI for test boards for 1527.
