This configuration is typical in an Ethernet Wall Adapter application. In PHY mode, the SIP is configured to be a Physical Medium Dependent (PMD) or PHY controller. In this configuration, an external MAC controls the SIP; this configuration is typical in an embedded application, such as a set-top box. Regardless of which mode is used, the SIP can be configured to use one of below protocols:   MII (100 Mbps max) Complies with 802.3(u) RGMII (1000 Mbps max) Supports RGMII v1.3 with internal 2ns delays The MAC and PHY configurations support 10 and 100 Mbps in half and full-duplex, and 1000 Mbps in full duplex mode only. When the RGMII interface is used, regardless of the speed, only full-duplex is supported. Flow control is supported in half-duplex using “back-pressure” preamble assertion, and using pause packets in full-duplex mode. The Ethernet interface includes the management data interface for MAC and PHY controller functions. The Ethernet MAC module implements a standard Ethernet MAC function. The Ethernet MAC will be connected to an external Ethernet PHY function. The MAC configuration provides bridging between Ethernet and PLC. The PHY configuration emulates Ethernet PHY functionality and provides PLC connectivity to devices designed to communicate over an Ethernet physical network. The Ethernet interface has separate transmit and receive packet buffering. When operating as a MAC the transmit FIFO is 2 KB and the receive FIFO is 16 KB. When operating as a PHY controller, the transmit FIFO is 16 KB and the receive FIFO is 2 KB. techhelp@belf.com belfuse.com [4] Powerline Modules 500Mbps Module MII Bus Signals Pin Number Pin Name 30 31 32 33 MRX_D0 MRX_D1 MRX_D2 MRX_D3 34 35 37 COL MRX_CLK MRX_ERR 38 MRX_DV 39 40 41 42 MTX_D0 MTX_D1 MTX_D2 MTX_D3 43 44 45 CRS MTX_CLK MTX_EN I/O MAC Mode I I I I I O I I O Description PHY Mode O Transmit Data Bits. The PHY controller drives MRX_D[3:0] and the MAC core receives MRX_D[3:0]. MRX_D[3:0] transition synchronously with respect to MRX_CLK. For each MRX_CLK period in which MRX_DV is asserted, MRX_D[3:0] is valid. MRX_D0 is the least-significant bit. The PHY controller tristates MRX_D[3:0] in isolate mode. O Collision Detected. The PHY controller asserts COL when it detects a collision on the medium. COL remains asserted while the collision condition persists. COL signal transitions are not synchronous to either the MTX_CLK or the MRX_CLK. The MAC core ignores the COL signal when operating in the fullduplex mode. The PHY controller tri-states COL in isolate mode. O Receive Clock. MRX_CLK is a continuous clock that provides the timing reference for the transfer of the MRX_DV and MRX_D[3:0] signals from the PHY controller to the MAC core. The PHY controller sources MRX_CLK. MRX_CLK frequency is equal to 25% of the data rate of the received signal on the Ethernet cable. The PHY controller tri-states MRX_CLK in isolate mode. O Receive Error. The PHY controller asserts MRX_ERR high for one or more MRX_CLK periods to indicate to the MAC core that an error (a coding error or any error that the PHY is capable of detecting that is otherwise undetectable by the MAC) was detected somewhere in the current frame. MRX_ERR transitions synchronously with respect to MRX_CLK. While MRX_DV is de-asserted, MRX_ERR has no effect on the MAC core. The PHY controller tri-states MRX_ERR in isolate mode. O Receive Data Valid. The PHY controller asserts MRX_DV to indicate to the MAC core that it is presenting the recovered and decoded data bits on MRX_D[3:0] and that the data on MRX_D[3:0] is synchronous to MRX_CLK. MRX_DV transitions synchronously with respect to MRX_CLK. MRX_DV remains asserted continuously from the first recovered nibble of the frame through the final recovered nibble, and is de-asserted prior to the first MRX_CLK that follows the final nibble. The PHY controller tri-states MRX_DV in isolate mode. I Transmit Data Bits. The MAC core drives MTX_D[3:0] and the PHY controller receives MTX_D[3:0]. MTX_D[3:0] transitions synchronously with respect to MTX_CLK. For each MTX_CLK period in which MTX_EN is asserted, MTX_D[3:0] is valid. MTX_D0 is the least-significant bit. The PHY controller ignores MTX_D[3:0] in isolate mode. O Carrier Sense. The PHY controller asserts CRS when either transmit or receive medium is non-idle. The PHY de-asserts CRS when both transmit and receive medium are idle. The PHY must ensure that CRS remains asserted throughout the duration of a collision condition. The transitions on the CRS signal are not synchronous to either the MTX_CLK or the MRX_CLK. The PHY controller tristates CRS in isolate mode. O Transmit Clock. MTX_CLK is a continuous clock that provides a timing reference for the transfer of the MTX_EN and MTX_D[3:0] signals from the MAC core to the PHY controller. The PHY controller sources MTX_CLK. The operating frequency of MTX_CLK is 25 MHz when operating at 100 Mbps and 2.5 MHz when operating at 10 Mbps. The PHY controller tri-states MTX_CLK in isolate mode. I Transmit Enable. A high assertion on MTX_EN indicates that the MAC core is presenting nibbles to the PHY controller for transmission. The SIP MAC core asserts MTX_EN with the first nibble of the preamble and keeps MTX_EN asserted while all nibbles to be transmitted are presented to the MII. MTX_EN is de-asserted prior to the first MTX_CLK following the final nibble of the frame. MTX_EN transitions synchronously with respect to MTX_CLK. The PHY controller ignores MTX_EN in isolate mode. techhelp@belf.com belfuse.com [5] Powerline Modules 500Mbps Module RGMII Bus Signals Pin Number Pin Name I/O MAC Mode PHY Mode Description 30 31 32 33 35 RD0 RD1 RD2 RD3 RXC I O Transmit Data Bits.

Connect to an external Ethernet PHY. This reset output is a stretched version of the RESET# input. O 25MHz Clock Out. This output is a dedicated clock output that can be used to drive the clock input on an external Ethernet PHY. This clock output is only available when the Powerline chipset is configured in MAC mode, and not in PHY mode of operation. Note that if this output is used, it is strongly advised that the corresponding PHY_RST# signal also be connected to the external Ethernet PHY. 49 PHY_CLK Coupling Interface Pin Number Pin Name I/O Description 6 TXRX+ I/O 100R differential TX/RX+ Powerline data, connects to coupling transformer 7 TXRX- I/O 100R differential TX/RX- Powerline data, connects to coupling transformer Special care must be taken during PCB layout of the coupling interface signals. Route differential pairs close together and away from all other signals. Route each differential pair on the same PCB layer. Keep both traces of each differential pair as identical to each other as possible. Wide copper is needed here to support current density of up to 70MHz. These high frequencies result in higher resistance due to skin effect. The wide traces also accommodate high transient currents caused by voltage spikes. Trace widths between the module and the coupling transformer must be no less than 0.020” (0.5 mm) and should be no greater than 0.030” (0.75 mm). Use of the Bel Fuse 0557-7700-36 or 0557-7700-42 Powerline couplers is recommended. Details can be found on the Powerline Couplers datasheet.

The waveform is to correspond to the polarity of the AC live waveform. For dry wire or DC safety this should be connected to VCC via a pull up (10kΩ). This information synchronizes the channel adaptation of the Powerline chipset to the line cycle periodic noise present on the power line. 24 ZC_IN techhelp@belf.com belfuse.com [14] Powerline Modules 500Mbps Module Configuration Options The Powerline chipset Ethernet Mode and boot options are selected by the initial condition of GPIO pins. If a GPIO pin is not used and its internal strapping resistor sets the booting option correctly, then the pin may be left unconnected. If a GPIO pin is not used but the internal strapping resistor sets the booting option incorrectly, then the pin must be pulled high or low to the correct booting option by an external resistor. All pull-up/pull-down resistors should be 3.3kΩ. Many GPIO pins are driven by firmware for LED output immediately after boot up so connecting these GPIO directly to ground or VDD is not permitted.

IOH = -4 mA for all other digital interfaces. 0804-5000-18/24 to 0804-5000⬜51 Compatibility The 0804-5000⬜51 SIP has been designed to be backward compatible with the existing 0804-5000-18/24 within the limits of the chipset utilized. As such there are a few minor limitations and full product testing should be conducted following an upgrade.   The maximum Ethernet data rate will be 10/100Mbits as the 0804-5000⬜51 utilizes the slower MII interface. Not all MII PHY’s have been tested so careful consideration should be made in regards to track lengths. To ensure correct operation any Pull up/downs GPIO straps should be changed from 10kΩ to 3.3kΩ. Design Notes Follow below table for unused signal lines: GPIO[11:0] PHY_CLK PHY_RST#    MRX_ERR COL CRS ZC_IN Action if signal not used Leave unconnected    Pull down by 10kΩ resistor  Pull up by 10kΩ resistor Special attention must be made to the RGMII interface lines on the 0804-5000⬜50. The RGMII interface uses 12 High speed data (125 MHz DDR) lines, control and clock signals, care must be taken to ensure signal integrity. The electrical lengths of the traces are divided into two match groups. Group 1 Group 2 TXC RXC TX_CTL RX_CTL TD[3:0] RD[3:0] Within each match group the maximum trace length should be less than 2 inches (50 mm) and the electrical length must match within 5%. These signals where possible should be routed on internal layers. In MII mode (0805-5000⬜51) the maximum data rate is 25 MHz, so although signal integrity is important it is not as critical as that of RGMII. techhelp@belf.com belfuse.com [17] Powerline Modules 500Mbps Module Mechanical Horizontal Mount - Industrial Temperature with Heatsink techhelp@belf.com belfuse.com [18]
