Robust Operation with Connector Interface to 110VAC
and 220VAC Inputs
Easy Evaluation of the MAX22707 in Different
Configuration Modes
EV Kit is USB Powered with Optional Power from
Terminal Block
Fully Assembled and Tested
Proven PCB Layout
RoHS Compliant
Ordering Information appears at end of data sheet.
Procedure
The EV kit is fully assembled and tested.
The default jumper settings in lowpass configuration
section configure the MAX22707 (U7) to operate in Type 3
mode (full wave rectified input).
The default jumper settings in bandpass configuration
section configure the MAX22707 (U8) to operate in Type 1
single-ended mode.
Follow the steps to verify board operation:
See Table 1 Jumper Positions and Configurations
See Table 2 Header Description
Refer to the MAX22707 DS on different input types
(Type 1-4)
1. Verify that all jumpers are in default positions (Table 1).
2. Power the EV kit with a micro-USB cable to a PC or 5V
adaptor at the J9 micro-USB connector. Alternatively,
the terminal block J6 can be used to power the EV kit
from a benchtop power supply when J9 is not used.
3. Connect an oscilloscope probe at ZCO_A_OUTPUT
J12(2) and ZCO_B_OUTPUT J13(2).
4. For evaluating the LPF mode, a shunt is installed
across J1 (1-2). Verify the VCCA LED is green,
indicating there is power available to the LPF section.
To evaluate the BPF mode, skip step 10 of the
procedure.
5. With the AC supply turned off, connect the line terminal
to LINE connector J20. Connect the neutral terminal to
NEUTRAL connector J22.

6. Turn on the AC supply and observe for digital output
transitions at ZCO_A_OUTPUT on the oscilloscope.
7. Disable the AC supply and power supply in that order
after evaluation.
8. To evaluate other input types for LPF mode, see Table
3 for all modifications and configuration settings and
follow steps 2-7.
9. Alternatively, to observe for AC input (attenuated lowvoltage level) and ZCO output at the high voltage side,
the oscilloscope power supply must be floating, and the
oscilloscope probes must be connected from the test
points provided at INP_LP, INM_LP, and J27 with
respect to the high voltage side ground GNDF.
10. For evaluating the BPF mode, install a shunt across
J1(2-3). Verify VCCB LED is green, indicating power is
available to the BPF section.

11. With the AC supply turned off, connect the line terminal
to LINE+ connector J15. Connect the neutral terminal
to LINE- connector J16.
12. Turn on the AC supply and observe for digital output
transitions at ZCO_B_OUTPUT on the oscilloscope.
13. Disable the AC supply and power supply in that order

14. To evaluate other input types for BPF mode, see Table
4 for all modifications and configuration settings and
follow steps 11-13.
15. Alternatively, to observe for AC input (attenuated lowvoltage level) and ZCO output at the high voltage side,
the oscilloscope power supply must be floating, and the
scope probes must be connected from the test points
provided at INP_BP, INM_BP, and J28 with respect to
high voltage side ground GNDF.

Detailed Description of Hardware
The MAX22707 EV kit provides an easy to use and flexible solution for evaluating the MAX22707, a low power precision
zero-crossing detector. The EV kit comes with two MAX22707 configured independently in lowpass mode and bandpass
mode, high voltage AC input interface, and input attenuation network to evaluate the device and the system.
The EV kit comes with both the LPF and BPF sections on the high voltage isolated side (HV side) are configured in default
modes (see Table 1). The jumper shunts provided on the logic side are used to select different configurations within each
section. Alternatively, the headers (J12) and (J13) on the logic side can be used when externally driving the logic signals
to configure the MAX22707 devices (U7) and (U8).
The default configuration for the LPF section is to accept Type 3 full wave rectified input (U7).
The default configuration for the BPF section is to accept Type 1 single-ended sine wave input (U8).
Device Powering Options
The MAX22707 EV kit is entirely powered from either the micro-USB connector (J9) or the terminal block (J6).
Alternatively, the EV kit can be powered using +3.5V to +5.5V supply applied to terminal block J6. The power supplied
generates isolated power on the isolated high voltage side (HV side) section. The MAX258 transformer driver and
transformer T1 convert logic side power to supply either VCCA (LPF section) or VCCB (BPF section).
At a given time, only one of the sections (LPF or BPF) can be evaluated. To evaluate the LPF section, a shunt is installed
at jumper J1 across 1-2, and to evaluate the BPF section, a shunt is installed at jumper J1 across 2-3.
Evaluating Different Input Types
The high voltage input resistor network has series resistance >100kΩ to the AC interface connectors. The resistor divider
converts the line voltage applied across connectors LINE (J20) and NEUTRAL (J22) to low voltage that MAX227070 (U7)
can handle. For the Type 1 and Type 2 single ended inputs (SE), a shunt across jumper J23 is installed for converting a
typical 220VAC signal to 2Vpk-pk. When evaluating the Type1 and Type 2 inputs, the input diode bridge must be modified
as per Table 3 . To evaluate in Type 2 input mode, install a shunt across jumper J24 (1-2) to bias the INM input at 1.25V.
To evaluate in Type 1 input mode, install a shunt across jumper J24 (2-3) to bias the INM input at ground GNDF.

To evaluate the Type 3 and Type 4 rectified inputs, jumper J23 is removed to convert a typical 220VAC signal to
2Vpk-pk. When evaluating the Type 4 input, the input diode bridge must be modified as per Table 3.
Table 3 shows jumper configurations required to configure the MAX22707 (U7) in different LPF modes. For more
information about the input types, refer to the MAX22707 data sheet.

The high voltage input resistor network has series resistance >200kΩ to the AC interface connectors. The resistor divider
converts the line voltage applied across connectors LINE+ (J15) and LINE- (J16) to low voltage that MAX227070 (U8)
can handle. The input network converts a typical 220VAC signal to 2Vpk-pk.
To evaluate Type 1 or Type 2 SE Inputs, a shunt is applied at jumper J19. To evaluate Type 1 single-ended input, a shunt
is applied across the jumper J19 (2-3) that provides a 0V (GNDF) bias to the input network. To evaluate Type 2 SE input,
a shunt is applied across jumper J19 (1-2) that provides 1.25V bias to the input network. To evaluate SE inputs across
LINE+ and LINE- in BPF mode, a shunt across jumper J17 is not installed.
A shunt across Jumper J17 is used to evaluate Type 1 or Type 2 differential inputs (DF). A shunt across jumper J17 (23) provides a 0V bias when Type 1 input is used. A 0.625V bias is provided when a shunt is applied across J17(1-2) to
evaluate Type 2 DF input. To evaluate DF input across LINE+ and LINE- in BPF mode, a shunt across jumper J19 is not
installed.

Input Attenuation Network
The input series resistance seen across the high voltage AC connectors must be >100kΩ. The external high voltage input
needs to be divided down to acceptable signal levels of the MAX22707. High wattage resistors must be chosen to handle
the power dissipation during attenuation of the input signal. The input series resistance value at each high voltage AC
connector must be ≤ 1MΩ.
The user should be aware of the hazards associated with higher voltages, which could cause any of the associated test
points or circuit traces to have a hazardous potential.
Input Network Bias
The MAX38902 low noise LDO generates the bias for the input network. In LPF mode, U6 is configured to provide 1.25V
of bias to the INM input of the MAX22707 (U7) when a jumper shunt J24 is installed across (1-2).
The device U4 (MAX38902) provides 0.625V bias to the BPF input circuitry for differential inputs when a shunt is installed
across J17(1-2), and U5 provides 1.25V for single ended inputs when a shunt is applied across J19 (1-2).
IEC 61000-4 Transient Immunity Compliance
The typical application for MAX22707 requires to pass basic transient immunity standards as defined by IEC 61000-4-x,
covering -2 for Electrostatic (ESD), -4 for Electrical Fast Transient/Burst (EFT), and -5 for Surge immunity. The MAX22707
EV kit includes circuitry to support testing to these standards to support ±6kV line-to-EGND (Earth GND) and line-to-line
surge, ±8kV contact ESD, and ±15kV air gap ESD. TVS diode (D9) provides protection from ESD voltage applied at INM
input. The EV kit includes circuitry to support up to ±3kV EFT with default components included.
See Figure 1 for connections and configuration used in high voltage immunity testing. It shows the disconnected jumper
sections and connections in red, indicating the supporting devices are disconnected from the active circuitry and are not
part of the high voltage immunity testing. Only the input resistive network and MAX22707 are considered for the immunity
compliance.
