REVISION SUMMARY
Revisions to other versions this document are as follows:
Revision C to D
1. Corrected reversal of Figure 4 and Figure 5 in LED section.
2. Changed ECL to PECL.
Revision D to E
1. Added GPSI timing and diagrams
2. Added Industrial Temperature support
Revision E to F
1. Minor edits
Revision F to G
1. Minor edits
Revision G to H
1. PHYAD pins: Specified using resistors in the range of 1 k
PHYAD pins must be set to addresses other than 00h.
2. DC Characteristics added: V
OLL
and V
OHL
3. DC Characteristics, added new values for: I
IL
, I
IH
, I
OZ.
Figure 6, Advanced LED Configuration, changes to Re-
ceive LED component changes.
Revision H to I
1. Added clarification to RX_CLK throughout document, which is active only while LINK is established. See pin de-
scription for more information.
2. Added Flow Control descriptions to registers 4 and 5
3. Register 21, bit 9 was reversed: 1 selects the standard LED configuration, while 0 selects the advanced LED
configuration
4. Register 21, bit 2 was changed to indicate EN_SCRM, Scrambler Enable; a 1 enables the scrambler. This reg-
ister is set by the SCRAM_EN pin
5. Maximum input voltage is 5.5 V; operating voltage for 5-V tolerant pins is 5.0 V
6. Minor edits
to 4.7 k for setting PHYAD pins. In GPSI mode,
