MAX9770 Evaluation Kit
Jumpers JU3, JU4, and JU5 control the SEL1, SEL2,
and SELM pins of the MAX9770 IC.
See Table 4 for JU3, JU4, and JU5 functions.
Table 4. JU3, JU4, and JU5 Jumpers Selection
Note: Refer to Table 2 of the MAX9770 IC data sheet for the multiplex/mixer settings.
Jumper JU6 controls the shutdown pin (SHDN) of the
MAX9770 IC. See Table 5 for shunt positions.
Table 5. JU6 Jumper Selection
Jumper JU7 provides an option to select the switching
frequency of the MAX9770 IC. See Table 6 for the vari-
ous shunt positions.
