INTEGRATED GIGABIT MAC WITH MARVELL 88E1111 DRIVER

The fiber transceiver is connected via the serial interface pins to the PHY device. Serializer DESerializer, used to convert from serial parallel. There is one supply option for VDDO: Idles will be transmitted out the copper transmitter. Table 27 shows the mode to select digital interfaces connecting to fiber media. In the 88E device, an advanced DPLL is used to recover and track the clock timing information from the receive signal.

I can’t see why a specific port should impose such a severe limitation. The COMA low power mode cannot be enabled as long as hardware reset is enabled. When Auto-Media detect is enabled, either register set can be read or written to by selecting Register Regis t er Addre ss If the user does not wish to transmit additional next pages, then the next page bit Register 4.

The 88E device uses marvepl mixed-signal processing to perform equalization, echo and crosstalk cancellation, data recovery, and error correction at a gigabit per second data rate.

Do not use Marvell products in these types of equipment or applications.

When the XTAL2 pin is not connected, it should be left floating. This document contains specifications on a product that is in final release.

mavrell If the last byte is odd, it is held internally by the Slave, but is not written to the Slave register. Need to update Registers 0.

TBI Receive Data code group [7: In BASE-T mode, receive polarity errors are automatically corrected based on the sequence of idle symbols. Marvell assumes no responsibility, either for use of these products or for any infringements of patents and trademarks, or other rights of third parties resulting from its use.

If it’s possible then we want to use lwip with this MAC. Marvell products are not designed for use in life-support equipment or applications that would cause a life-threatening situation if any such products failed.

In the intfgrated of a three pair cable additional pair 4,5 or 7,8 – but not both the same downshift function for two-pair cables applies. The 88E device employs an advanced baseline wander cancellation circuit to automatically compensate for this DC shift.

Internally divided to 25MHz. However, this is not indicated by Register The MDI pins should be terminated externally with ohm differential wth and connected to an RJ connector through magnetics.

The DTE power function can be enabled by writing to Register If so, the 88E device and the wihh device negotiate the speed and duplex with which to operate. Refer to Register Similarly, for modes other than the GMII, the media selection should be strapped to copper.

Note that for these settings to take gigaabit a software reset must be issued. Speed, duplex, page received, and Auto-Negotiation completed status are also available in registers 17 and If the Slave does not Acknowledge the device address, but some time integratee in the transfer cannot receive any more data bytes, the Master must abort the transfer.

Upon initialization, the initial scrambling seed is determined by the PHY address. A software update is required to update 0.

This prevents multiple 88E device from outputting the same sequence during idle, which helps to reduce EMI. The polarity and magnitude of the reflection together with the distance will indicate the type of discontinuity.

The user must program the MAC with this information in some other way e.

The depth of the transmit and receive FIFOs can be independently programmed by programming register bits TCK contains an internal kohm pull-up resistor. A sequential read is initiated by either a current or random address read.
