Safety NotesWarning: EXERCISE CAUTION WHEN LIVE AC VOLTAGES ARE PRESENT!Standard ESD precautions must be taken when handling electronic equipment.Exercise extreme caution handling the hardware and connecting test equipment to the non-isolated portion of the ZENO modem board (Figure 1, highlighted in red). Ignoring the safety requirements can lead to shock, injury, and damage of the hardware.

Figure 1. ZENO Board Modem



Evaluation Kit DescriptionThe MAX79356 EV kit contains all the hardware required for point-to-point communication, utilizing Simple-MAC or Full-MAC firmware. The communication between the two modem boards can be on a powered line (up to 230VAC or 300VDC), or on cold wire.Figure 2 illustrates the connection.

Evaluation Board The EV kit contains two identical MAX79356 evaluation boards featuring a narrow-band G3-PLC modem.

Power Supply Each evaluation board is powered by a 15VDC power adapter connected to J1. A linear regulator (U2) provides the 3.3VDC supply to the MAX79356 OFDM modem and the MAX44211 line driver (DVDD). The 15VDC directly powers the line driver analog supply (AVDD).The MAX79356 internal linear regulator supplies its internal 1.2VDC digital logic from the 3.3V supply.

MAX79356 OperationsZENO features two hardware UARTs (UART0, UART1). UART0 is used by the host CPU for data communication, control of the modem, and firmware updates. UART1 is used for debugging purposes.

ZENO communicates with the host processor through a serial line interface protocol (SLIP) over the UART0 inter-face. The ZENO firmware supports operation at either 115,200bps or 230,400bps (depending on FW) without flow control. Refer to the ZENO G3-PLC Modem Interface Specification for details on the host communications protocol.An SPI interface is available (master/slave) in ZENO. Refer to the data sheet or firmware release notes for availability of firmware support for SPI.

Firmware UpdateThe host processor can update the MAC and PHY firm-ware through UART0 using a specific serial loader pro-

tocol. To go to serial loader mode, the PROG input pin is driven low and held low while the reset pin RSTN is pulsed low.

Line Driver Gain ControlThe MAX79356 controls the gain inputs of MAX44211 the line driver (GAIN0 and GAIN1), the gain can be set to 6, 12, 15 and 18 according to Table 1.

Line Driver StatusThe MAX79356 also acquires the status of the line driver, the status is also available at the test points TP15 (Status 0) and TP16 (Status 1). Table 2 describes the status conditions.

MAX44211 Line DriverThe evaluation board includes the MAX44211 power amplifier (line driver) that drives the coupling trans-former. The MAX44211 provides two digital inputs for the gain selection (GAIN0 and GAIN1) controlled by the MAX79356. The MAX44211 also provides two digital out-puts signaling the status of the driver (temperature and current alarms and shutdowns).The MAX44211 provides an input (ISET) for setting its maximum output current. In the evaluation board, resistor R22 is connected between this input, and GND provides the current-limit setting. The evaluation board’s PCB includes a copper area for thermal dissipation. A heatsink can be added at the bottom of the PCB for additional power dissipation. A dual-side adhesive thermal strip secures the heatsink to the PCB. Figure 4 illustrates the location of the heatsink.

Zero-Crossing DetectionThe evaluation board includes a zero-crossing detection circuit. The circuit is isolated from the MAX79356 through an optocoupler (U6). The zero-crossing circuit generates the pulses on the rising edge of the zero crossing of the AC input sine wave.

Coupling Circuit and ProtectionsThe modem circuitry is coupled to the mains through the transformer (TX1) and the high-voltage coupling capaci-tor (C37). The transformer provides both signal coupling (Tx and Rx) and galvanic isolation, while the capacitor provides DC blocking and attenuation at low frequencies.There are three main protections in the coupling circuit. The line driver is protected by four Schottky diodes. The diodes are clamping overvoltage kickbacks from the TX1 transformer. Diode Z3 is a low-voltage TVS placed between the TX1 transformer and the coupling capacitor. The main function of this diode is to clamp any overvoltage resulting from high dV/dt on the AC mains (i.e., caused by interruptions of the AC mains). Diode Z2 is a high-voltage TVS. This diode mainly protects from high-voltage transients on the mains.Note: While diode Z2 protects the input circuitry (zero-crossing detection and coupling) against high-voltage transients, it does not guarantee the circuit to be protected as per IEC 61000-4-5 Standard. The fuse (F3) protects the input circuit against overcurrent that could result from erroneous wiring or operation errors.
