Support 8 RMII ports for 10M/100M operation, and really meet 100M_hub class_2 spec when connect with external QPHYceivers. The MTD658 provides two Inter-repeater stacking bus for 10M and 100M expansion each, easily stack to 4 units without any external arbitration logic. If using external arbitration logic and proper bus driver, can stack to 6 units and up. The build_in 2 port switch, support 2k MAC addresses filtering, and use low cost asynchronous high speed SRAM (128k*8) one pcs only for packet buffering. This 2 port switch can also be configured to be up_link switch when hub is under slave mode.

3.0 FUNCTIONAL DESCRIPTIONS
MTD658
The MTD658 is conformed to IEEE802.3 chapter 9 and IEEE802.3u clause 27 specifications. The MTD658 provides 8 Redused MII interfaces and an embedded two port switch to construct a 10M/ 100M dual speed Hub application. Two Inter-Bus are also provided for stackable 10M/100M dual speed Hub application. The MTD658 functions are described as follows:
3.1 Repeat and data handling
8 independent RMII ports integrated with IEEE802.3 chapter 9 and IEEE802.3u clause 27 repeater functions simultaneously. MTD658 embedded two Hub cores (10M and 100M) ,and each dedicated RMII interface port can get per port' speed information from per port speed input pin, and then s MTD658 will switch individual port to their appropriated Hub core functions (10M or 100M). The MTD658 receive packets from each RMII ports, and redirect port' input packet to 10M or 100M s Hub core according each port' speed. The internal IEEE802.3 chapter 9 or IEEE802.3u clause 27 s repeater main state machine will starts to repeat the input packet to all ports except the input port. If larger than or equal to two ports have input packet simultaneously, this will be treated as a collision, and MTD658 will assert an arbitrary JAM pattern to all ports'output until collision event disappear and network is idle.
3.2 Partition
The MTD658 provides 10M/100M auto partition/reconnection functions to guarantee the network segment performance by means of dectecting a consecutive collisions. Each dedicated RMII port has implement a individual 10M/100M auto partition/reconnection state machine. If port' consecutive collis sion number over or equal to CClimit (10M CClimit default is 32, 100M CClimit default is 64), this port will be partitioned. Reconnection will occurs after a larger than 512 bit time packet was received or transmitted from this partitioned port without any collision. When port is under partition state, MTD658 will not accept any input messages from this port (just monitor input message), but will continue output repeated messages to this partition port. Some new partition criterions are also implement, such as long_collision_partition event, jabber_partition event. In 10M/100M partition state machine, longer than 1024 bit time continueous collision will force port enter partition state. In 100M partition state machine, if port enter jabber_on state, this port will be partitioned. In 10M, jabber_partition function is not implemented.
3.3 Jabber
The jabber protect function is used to prevent an illegally long packet reception. After the MTD658 received a longer than 65536 +/- 6.25% bit times packet, this receive port` receive/transmit path will be s inhibited until carrier is no longer detected.
3.4 MII Setting
Due to HUB is an half duplex device, the MTD658 need to force all connected phsical devices to work in half duplex environment. The MTD658 will setting all PHY' SMI register 4' half/full duplex bit during s s power on, and than restart auto-negotiation procedure to work in half duplex mode, and the PHY' s device ID should be set by PCB maker from 5' h04 - 5' h0b(port0-7).
3.5 Inter-Bus Interface
Two Inter-Bus Interface are provided by the MTD658, One is 10M Inter-Bus Interface, the other is 100M Inter-Bus Interface. The Inter-Bus interface is designed for stackable hub application. For each domain, up to 4 MTD658s can be stacked through this Inter-Bus without any external arbitration logic. The InterBus Interface includes IMASTER, IDATA (100M: use IDAT<3:0>, 10M: use only IDAT), REQOUT, REQIN0-2, ICLK, IACKB, ICOLB pins. IMASTER decide which MTD658 can arbitrate the Inter-Bus, and only one MTD658' IMASTER can be tie high in a stackable Hub. IDATA are synchronous with s ICLK. The MTD658 output REQOUT to inform Inter-Bus Interface that it need the Inter-Bus right. When IACKB is asserted by Inter-Bus master after REQOUT asserted, the MTD658 which asserted REQOUT will get the bus right and put the transmit data into IDATA. If the MTD658 did not assert
9/17 MTD658 Revision 2.0 17/03/2000
MYSON TECHNOLOGY
MTD658
REQOUT , but IACKB is asserted, means this MTD658 can get data from IDATA bus. When only one MTD658 output REQOUT to Inter-Bus Interface, IACKB will be asserted by Inter-Bus master device, If larger than two MTD658' REQOUT were asserted, Inter-Bus master will not assert IACKB , but will s assert ICOLB to inform all the connected MTD658s. The Inter-Bus interface can also be programmed to EXT_ARB mode, using LEDDAT pin' jumper sets ting. In this mode, Inter-Bus interface need an external arbitration logic to arbitrate Inter-Bus operation. And in this mode, the stackable capability is not limitted by the MTD658' REQIN pins number. s
3.6 10M/100M packet Switch
The MTD658 inplements a 10/100M two port switch for 10M/100M packet switching. Total 2K address entrys are provided for packets'SA learning and DA routing; and alsoprovide automatic aging function ( aging time = 300secs). The input packet from 10MHub ( or 100M Hub) will be stored to external memory first, while packet is good for forward ( CRC chech ok, 64Bytes < length > 1518Bytes, and not local packets ) , than forward this packet to 100M Hub (or 10M Hub).
3.7 Uplink Switch Port
The MTD658 can config one switch port as an uplink switch port. When UPSWEN pin is high, and IMASTER pin is low, one of the intenal switch port is connect to 100M HUB, the other is connected to RMII port 7. In uplink switch mode, port 7 can work in 10M/100M(from SPEED7 pin), half/full duplex(from P7FULL pin) mode.
3.8 Memory Interface
The MTD658 use asynchronous SRAM as two port switchs'packet buffers, total has 128K byte external memory for packet buffering.
3.9 MII management
The MTD658 can be managed through MDC, MDIO pins. The MTD658 implements 3 MII registers for function control and status report (see Section 4.0 on page ). The management frame format is compliant to IEEE802.3u clause 22, and the device ID is fixed to 5' internally. h1f
3.10 LED display
The MTD658 implements three display modes, port RX activity, 10/100M domain collision, port partition. The LED data pin LEDDAT is high actived. One strobe pin LEDCLK(24 burst clock/per 42ms) is used to latch serial LEDDAT information, and user can shift the latched data into byte aligned shift register to drive LEDs.
4.0 Registers

Note: 1.Dimension D1 & E1 do not include mold protrusion. But mold mismatch is included. Allowable protrusion is .25mm/.010" per side. 2.Dimension B does not include dambar protrusion. Allowable dambar protrusion .08mm/.003". Total in excess of the B dimemsion at maximum material condition. Dambar cannot be located on the lower radius or the foot. 3.Controlling dimension : Millimeter.
