NOTES;
1) UNIPOLAR OPERATION
A SIDE + CONNECT 2.43k
RES. FROM TP1 TO TP5.
A SIDE – CONNECT 2.67k
RES. FROM TP5 TO TP6.
B SIDE + CONNECT 2.43k
RES. FROM TP2 TO TP4.
B SIDE – CONNECT 2.67k
RES. FROM TP4 TO TP3.
2) ABOVE UNIPOLAR RESISTOR VALUES ARE
NOMINAL AND MAY HAVE TO BE ADJUSTED
DEPENDING ON OFFSET OF DUT.
3) ENCODE SOURCES
A) FOR NORMAL OPERATION, A 40MHz TTL CLOCK
OSCILLATOR IS INSTALLED IN U1 AND U2. THERE
IS A 51
RESISTOR BETWEEN J15 AND J16.
J17 AND J18 ARE OPEN.
B) FOR EXTERNAL SQUARE WAVE ENCODE, INPUT
SIGNAL AT J1 AND J8, REMOVE U1, U2, JUMPERS
J15 AND J16. CONNECT JUMPERS J17 AND J18.
C) FOR EXTERNAL SINE WAVE ENCODE, INPUT
SIGNAL AT J1 AND J8, REMOVE U1, U2, R9, R11,
JUMPERS J15 AND J16.
CONNECT JUMPERS J17 AND J18.
4) POWER (5VD) FOR DIGITAL OUTPUTS OF THE
AD10242 IS SUPPLIED VIA PIN 1 OF EITHER J9 OR J10
(THE DIGITAL INTERFACES). TO POWER THE EVAL.
BOARD WITH ONE 5V SUPPLY, JUMPER A WIRE
FROM E1 TO E4 (CONNECTED AT FACTORY).
