MAX7314 Evaluation Kit
The MAX7314 EV kit provides a jumper (JU2) for con-
figuring the 2-wire serial address of the MAX7314. The
SCL, SDA, and AD0 PCB pads are provided for inter-
facing to the 2-wire serial address bus and configuring
the address, respectively. Table 2 lists the various
jumper options for configuring the 2-wire address.
The MAX7314 EV kit provides a jumper (JU3) to select
the BLINK pin’s signal source: the EV kit’s oscillator (U2,
U3), or a user-provided CMOS square-wave signal. The
square-wave signal is applied across the EV kit’s
BLINK_IN and GND board pads. Table 3 lists the vari-
ous jumper JU3 options for the BLINK signal source.

The MAX7314 EV kit features jumpers JU4 and JU5 to
set the EV kit’s oscillator frequency (from 0.7Hz to
3.0Hz). Additionally, jumper JU6 is provided to disable
the EV kit’s oscillator. Table 4 lists the various frequen-
cy selection options using jumpers JU4 and JU5. Table
5 lists jumper JU6 enable/disable options for inverters
U2 and U3.
The EV kit provides a switch (SW1) to reset the
MAX7314 IC. Additionally, the EV kit provides a RST
PCB pad for using an external controller to reset the
device. Refer to the MAX7314 IC data sheet for addi-
tional functions of the RST pin.
