signal and the KSZ8041NL decodes a data frame. The receive clock is kept active during idle periods in between data
reception.
SQE and Jabber Function (10Base-T only)
In 10Base-T operation, a short pulse is put out on the COL pin after each frame is transmitted. This SQE Test is required
as a test of the 10Base-T transmit/receive path. If transmit enable (TXEN) is high for more than 20 ms (jabbering), the
10Base-T transmitter is disabled and COL is asserted high. If TXEN is then driven low for more than 250 ms, the 10Base-
T transmitter is re-enabled and COL is de-asserted (returns to low).
Auto-Negotiation
The KSZ8041NL conforms to the auto-negotiation protocol, defined in Clause 28 of the IEEE 802.3u specification. Auto-
negotiation is enabled by either hardware pin strapping (pin 30) or software (register 0h bit 12).
Auto-negotiation allows unshielded twisted pair (UTP) link partners to select the highest common mode of operation. Link
partners advertise their capabilities to each other, and then compare their own capabilities with those they received from
their link partners. The highest speed and duplex setting that is common to the two link partners is selected as the mode
of operation.
The following list shows the speed and duplex operation mode from highest to lowest.
Priority 1: 100Base-TX, full-duplex
Priority 2: 100Base-TX, half-duplex
Priority 3: 10Base-T, full-duplex
Priority 4: 10Base-T, half-duplex
If auto-negotiation is not supported or the KSZ8041NL link partner is forced to bypass auto-negotiation, the KSZ8041NL
sets its operating mode by observing the signal at its receiver. This is known as parallel detection, and allows the
KSZ8041NL to establish link by listening for a fixed signal protocol in the absence of auto-negotiation advertisement
protocol.
The auto-negotiation link up process is shown in the following flow chart.
