TMThe MAC-PHY interface of technology (" MPI "), this interface is set up with standard mode, supports the communication between PHY layer 10 and the MAC layer 20, and PHY layer 10 and MAC layer 20 communicate with distinct device.
Fig. 2 A-2B has constituted a table together, and this table shows attribute via the example signal of interface 1 (referring to Fig. 1) communication (that is, the signal that is designated input (" I ") comes from MAC layer 20 and is the input of PHY layer 10) from the angle of PHY layer 10.
The CPU that links to each other with MAC layer 20 can utilize interface 1 via MAC layer 20 visit PHY layer 10 (see figure 1).CPU can do like this by serial ports, be configured, initialization and debugging.Configured port can utilize PHY_CLK 134 (see figure 1) signals as serial clock.The general combination with serial line interface of agreement defines, to allow read and write access.
Fig. 3 is the sequential chart of MAC to PHY, and it shows from the timing of MAC layer 20 to PHY layer 10.MNG_DIR signal 124 can be used for being provided with the direction of transfer of data.
Fig. 4 has provided several mode of operation figure, as the 10 achievable replacement of PHY layer, wait and activity.When Reset Status, PHY layer 10 and MAC layer 20 become their signal into non-activity value usually.Reset signal is not the part at the MAC-PHY of this demonstration and description interface arrangement.Wait is the state when PHY layer 10 non-PHY layer 10 when movable in RX or TX.When wait state, PHY layer 10 is by closing unnecessary function and then reducing power consumption.But, the parameter registration device generally keeps active state to carry out read-write operation.When PHY_STRT 132 (see figure 1)s were determined, PHY layer 10 entered active state and keeps this state until the burst processing finishes.When active state, path MPD_TX 116 and/or MPD_TX 118 (seeing the interface 110 among Fig. 1) can be in active state.If when TX follows closely after the RX and RX when being not over yet after TX begins, MPD_TX 116 and MPD_TX 118 may be in active state.When active state, have only active path to open, other path should be closed.

Fig. 9 shows exemplary burst initialization (" burst initialization ").PHY_STRT 132 general burst delay times before first symbol of header appears at coaxial cable are identified (assert).MAC layer 20 can use the first of burst delay time to send the burst initiation parameter.When PHY layer 10 can use the second portion of burst delay time to happen suddenly first symbol that initialization points delays header appears at coaxial cable.When RX happened suddenly, PHY layer 10 generally began to obtain when the burst time-delay finishes.In case PHY_STRT 132 determines (assertion), though RX result just in process of transmitting, PHY layer 10 begins to read burst parameter from MAC layer 20.The burst general burst parameter of 400 bits that allows of initialization time sent to PHY layer 10 before burst.PHY layer 10 trigger may be 5 microseconds (" uS " or " μ S "), and the preceding time of burst of increase can be provided like this.
Figure 10 shows after RX handles the time-delay concluding time, and PHY layer 10 can begin to send RX burst result.RX handles delay time and generally measures to handling RX burst maximum delay from last sign-off of coaxial cable.The maximum time that Figure 11 shows transmission RX result parameter may be 33.8 μ S (854B).Figure 12 shows the initialization that happened suddenly of RX burst the possibility of result and interrupts.
Figure 13-16 shows the example feature as the data-interface of MPD interface 110 (see figure 1)s.
The MPD interface 110 of Fig. 1 generally comprises data/address bus, and for example the MPD_DATA bus 112, data enable signal, for example MPD_DATA_EN signal 114 and TX/RX signal, for example MPD_TX signal 116 and MPD_RX signal 118. Signal 116 and 118 General Definitions data/address bus 112 direction and generally can not activate simultaneously.MPD_RX signal 118 generally stopped before MPD_TX 116 sends to 20 transmission of MAC layer.Before the header of next TX burst began transmission, the afterbody of MPD_RX signal 118 can transmit by MPD_DATA 112.
Intermediate data space (" MDG ") is defined herein as the time between first symbol of last symbol of RX and TX load on the coaxial cable.During this space, all RX data generally are transferred to MAC layer 20, and can read enough data transmit after end of header.In certain embodiments, MDG can be 21.52uS in the bandwidth of 50MHz, certainly, also can use any suitable MDG.MDG generally comprises minimum interframe gap (" IFG ") and the minimum header time of 7.8us (10us-2.2us).In certain embodiments, in the 50MHz bandwidth, the minimum header time (size is that the minimum of 10 samples allows Cyclic Prefix, " CP " for minimum header, " P4 ") can be 13.72us, but can use any suitable minimum header time.In certain embodiments, this time can be 6.86us in the turbo pattern, but also can use any suitable minimum preamble time.
Intermediate symbols gap (" MSG ") is defined as in the coaxial cable last sign-off of RX and from the time between equipment first symbol of (as, consumer electronics (" CE ") equipment).During this gap, the FFT machine is generally finished the processing of last RX symbol, and IFFT generally finishes the processing of CE symbol, and a CE sample generally appears in the media when end of header.In certain embodiments, in the 50MHz bandwidth, MSG generally can be 9.08us, can certainly be any suitable MSG.In certain embodiments, under the turbo pattern (100MHz), MSG can be 8.44, can certainly be any suitable MSG.MSG generally includes minimum IFG and the short header time that comprises 7.8us (10us-2.2us).In certain embodiments, in the 50MHz bandwidth, the short header time can be 1.28us (L2), but can use any short header time.In certain embodiments, this time can be 0.64us in the turbo pattern, but also can use any suitable minimum header time.
IFG (seeing Figure 11 and 12) is between two bursty datas of transmission on the MPD_DATA bus 112, the aperture time on the MPD_DATA bus 112.IFG is generally the MAC time of internal delay time, and this time is generally 0.5us (is 25 cycles for PHY_CLK).
The timing of explanation PHY layer 10 now.Two times prerequisite (time_critical) path is generally arranged between RX burst and the TX burst in PHY:
Path A: FFT is to IFFT.Time between first symbol (CE) that last symbol and the IFFT of FFT end process RX bursty data begin the TX bursty data; With
Path B:RX data are to the TX data.Time between first bit that last bit and the TX bursty data of RX bursty data by interface 1 (see figure 1) begins to transmit by interface 1.
For path A, except the time from IFFT to the TX path, the time from the RX path to FFT generally adds up.For the B of path, except MPD_IFG, the time in all RX and TX path generally adds up.
Figure 13 and Figure 14 have provided the example of the RX path delay of time and TX path time respectively.
Refer again to two data bursts of transmission on MPD_DATA bus 112, as shown in figure 15, when first data bit of TX burst TX (1) via 112 transmission of MPD_DATA bus during up to last bit of this bursty data, MPD_TX signal 116 is generally confirmed by PHY layer 10.Figure 16 shows first data symbol of receiving from coaxial cable media (as, self adaptation constellation multitone (" ACMT ") symbol) beginning, and last bit of transmission RX burst is confirmed MPD_RX signal 118 on MPD_DATA bus 112.MAC layer 20 detects the affirmation of MPD_RX signal 118 usually, and locking network timer (" NT ") is for stabbing (" ATS ") time of advent.This ATS generally is used for comparing with the transmission time started, thereby NT and network controller NT is synchronous.When detection of end and two CE symbols arrive in the permissible range by the sample definition of predetermined number, generally with MPD_RX signal 118 release confirmation.Between the beginning header appear at media and the time between the MPD_RX signal 118 confirmed generally based on header type and CP.
