Description
The MT933 is a single chip 3.3V CMOS physical
layer solution from MII to the magnetics. It is designed
for 10BASE-T and 100BASE-TX Ethernet, based
on the IEEE 802.3 specifications.
The MT933 is compatible with the Auto Negotiation
section of IEEE 802.3u and provides all the support
needed for the 802.3 Full duplex specification.

... Intelligent power management (auto shutdown, auto wake) G Low Transmit Jitter Description The MT933 is a single chip 3.3V CMOS physical layer solution from MII to the magnetics designed for 10BASE-T and 100BASE-TX Ethernet, based on the IEEE 802.3 specifications. The MT933 is compatible with the Auto Negotiation section of IEEE 802 ...

... This data is synchronised to the rising edge of TX_CLK. To indicate that there is valid data for transmission on the MII, the MAC sets the TX_EN signal active. This forces the MT933 device to take in the data on the TXD[3:0] bus. This is serialised and directly encoded as Manchester data, before being output on the TXOP/TXON differential output for transmission through 1:Ö ...

... The synthesizer is To indicate that there is valid data for transmission on the MII, the MAC sets the TX_EN signal active. This forces the MT933 device to take in the data on the TXD[3:0] bus and replace the first octet of the MAC preamble with Start-of-Stream Delimiter (SSD) symbols to indicate the start of the Physical Layer Stream ...

... CRS de-assertion is between 19 and 23BT. 100Mb/s Transmit Errors If the MT933 detects that the TX_ER signal has gone active whilst the TX_EN signal is active, then it will propagate the detected error onto the cable by transmitting the symbol “ ...

... Reset Mode There are two types of reset in the MT933 - hardware and software. The hardware reset is activated by setting the RESET_N pin to logic 0, and holding it low for at least 100ns. This mode causes an over-all reset in the MT933 - both analog and digital circuitry are reset ...

... ANEN pin low or by setting bit 12 of register 0 to zero. If auto- neg is disabled, the MT933 will lose the link, and link will be re-established only after the MT933 control state machine has determined the speed using bits 13 and 8 of register 0 to determine speed and duplex respectively ...
