preface 8 lxt98xx multi-port 10/100 mbps repeaters specification update document number: 249355 revision number: 007 revision date: january 28, 2004 nomenclature errata are design defects or errors. these may cause the lxt98xx multi-port 10/100 repeaters? behaviors to deviate from published specifications. hardware and software designed to be used with any given stepping must assume that all errata documented for that stepping are present on all devices. specification changes are modifications to the current published specifications. these changes will be incorporated in any new release of the specification. specification clarifications describe a specification in greater detail or further highlight a specification?s impact to a complex design situation. these clarifications will be incorporated in any new release of the specification. documentation changes include typos, errors, or omissions from the current published specifications. these will be incorporated in any new release of the specification. note: errata remain in the specification update throughout the product?s lifecycle, or until a particular stepping is no longer commercially available. under these circumstances, errata removed from the specification update are archived and available upon request. specification changes, specification clarifications and documentation changes are removed from the specification update when the appropriate changes are made to the appropriate product specification or user documentation (datasheets, manuals, etc.). www.datasheet www.datasheet www.datasheet www.datasheet 4u 4u4u 4u .com .com .com .com 4 .com u datasheet

errata 12 lxt98xx multi-port 10/100 mbps repeaters specification update document number: 249355 revision number: 007 revision date: january 28, 2004 errata 1. data misplacement in extended packets problem: the tp_idl pulse is found in an extended data field when extending a packet length to 96 bits. implication: this issue is benign in networks since the packet extension is seen as a fragment. workaround: none. status: there are no plans to fix this erratum. 2. 100 mbps packet loss problem: in a unique network configuration involving stacked repeaters with mixed cable lengths, short ifgs (less than 9 bt) on the 100 mbps irb cause internal state machines to lose synchronization. the short ifg is caused when two ports (using short cables) experience a collision while a port transmission (using a long cable) reaches the repeater within 9 bt after the end of the collision. implication: when the next packet is sent, error codes (hs) are substituted throughout, resulting in packet loss and re-synchronization of the state machines by eop. the errored packet is retransmitted. workaround: none. status: there are no plans to fix this erratum. 3. inability to link in auto-negotiation mode problem: the lxt98xxa may be unable to establish a 100 mbps link in auto-negotiation mode with a link partner that is in auto-negotiation mode. implication: the lxt98xxa device may fail to establish a link when the lxt98xxa is in auto-negotiation mode (advertising 100 mbps capability) and attempting to establish a 100 mbps link with a link partner in auto-negotiation mode. the lxt98xxa outputs auto-negotiation fast link pulses (flps) at twice the specified width when link establishment fails. the link partner is unable to link with the lxt98xxa in this state. this erratum only occurs during link establishment through auto- negotiation. the device operates normally once link is established. linking with a link partner in forced 100 mbps, forced 10 mbps, or auto negotiation (advertising 10 mbps capability only mode) will not cause this erratum to occur. occurrence of this erratum increases as the lxt98xxa case temperature increases. the device has a low occurrence of this erratum at 25 o c. workaround: to prevent occurrence of this erratum: lxt9880a, lxt9860a (managed): disable auto-negotiation to avoid the problem. only link with link partners in forced 100 mbps, forced 10 mbps, or auto-negotiation with only 10 mbps capability advertised. lxt9883a/lxt9863a (unmanaged): only link with link partners in forced 100 mbps, forced 10 mbps, or auto-negotiation with only 10 mbps capability advertised. www.datasheet www.datasheet www.datasheet www.datasheet 4u 4u4u 4u .com .com .com .com 4 .com u datasheet
errata lxt98xx multi-port 10/100 mbps repeaters specification update 13 document number: 249355 revision number: 007 revision date: january 28, 2004 to recover if this erratum occurs: reset the lxt98xxa to take the port out of the double width flp state if the port is unable to link. minimizing operating temperatures reduces the occurrence of this erratum on all devices. status: there are no plans to fix this erratum. www.datasheet www.datasheet www.datasheet www.datasheet 4u 4u4u 4u .com .com .com .com 4 .com u datasheet
specification changes 14 lxt98xx multi-port 10/100 mbps repeaters specification update document number: 249355 revision number: 007 revision date: january 28, 2004 specification changes 1. ir10ena asserted to tpop/n active timing description: the minimum bit time for ir10ena asserted to tpop/n is reduced from 5bt to 4bt in table 42: 10 mbps irb-to-tp port timing parameter. implication: ieee 802.3 standard specifies a maximum bt (bit) time for twisted-pair timing. reducing the minimum bit time does not impact performance or ieee compliance. status: no fix. 2. tpip/n-to-ir100dv low timing description: the minimum bit time for tpip/n-to-ir100dv low is reduced from 18bt to 17bt in table 40: 100 mbps tp-to-irb timing parameters. implication: ieee 802.3 standard specifies a 46 bit time maximum for twisted-pair port to port timing. reducing the minimum bit time for twisted-pair por t to irb will not impact performance or ieee compliance. status: no fix. www.datasheet www.datasheet www.datasheet www.datasheet 4u 4u4u 4u .com .com .com .com 4 .com u datasheet

addenda 18 lxt98xx multi-port 10/100 mbps repeaters specification update document number: 249355 revision number: 007 revision date: january 28, 2004 addenda 1. 100base-tx receive jitter tolerance description: if a receive-link partner operating in 100base-tx generates transmit jitter greater than the ieee standard, the lxt9860/63/80/83 devices may produce errors within the reconciliation sublayer, which can result in failure to link or to sustain link. the lxt9860/63/80/83 devices will be enhanced to allow greater margin to the ieee standard. the identified change should allow greater design flexibility; however, customers are advised that reliance on such out-of-margin performance is at their own risk. status: implemented in stepping 5. 2. 10base-t jitter tolerance description: in some 10base-t input jitter applications, the lxt9860/63/80/83 device margin may be close to the ieee standard for input jitter tolerance. the lxt9860/63/80/83 devices will be enhanced to be optimally centered for 10base-t input jitter tolerance. the identified change should allow greater design flexibility; however, customers are advised that reliance on such out-of-margin performance is at their own risk. status: implemented in stepping 5. www.datasheet www.datasheet www.datasheet www.datasheet 4u 4u4u 4u .com .com .com .com 4 .com u datasheet
