Preface
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.).

Stepping / Revision Numbers
A “Stepping Number” is assigned when any product design update is released that changes the
device errata or specification. A “Revision Number” is assigned to each device tapeout, regardless
of impact to device errata or specification. The “Manufacturer’s Revision Number” may be read by
software from Register 13C, bits 31:28 in the LXT98xx repeaters.

Errata
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.
This issue is benign in networks since the packet extension is seen as a fragment.
Implication:
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
o
erratum at 25 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.

Errata
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.
There are no plans to fix this erratum.

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:
Status:
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.
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:
Status:
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 port to IRB will not impact performance or IEEE
compliance.
No Fix.

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.
