• Corrected reversal of Figure 4 and Figure 5 in LED section.
• Changed ECL to PECL.
• Added GPSI timing and diagrams
• Added Industrial Temperature support
• PHYAD pins: Specified using resistors in the range of 1 kΩ to 4.7 kΩ for setting PHYAD pins. In GPSI mode,
• DC Characteristics added: V
• DC Characteristics, added new values for: I
• Added Flow Control descriptions to registers 4 and 5
• Register 21, bit 9 was reversed: 1 selects the standard LED configuration, while 0 selects the advanced LED
• Register 21, bit 2 was changed to indicate EN_SCRM, Scrambler Enable; a 1 enables the scrambler. This register
• Maximum input voltage is 5.5 V; operating voltage for 5-V tolerant pins is 5.0 V
• Minor edits
• Changed resistor requirements to 1K to 4.7
• Minor clarifications to pin descriptions.
• Clarified GPSI/7-Wire mode operation.
• Changed Figure 1, 100BASE-FX termination.
• Clarified loopback section.
• Changes RESET minimum time to 155 µs from 10 ms.
• LEDs - replaced Tables 7, 8, and 9, added to clarify Advanced LED Mode Operation. Modfied Figure 5 and added
• Clarified Register 0, bit 15 RESET
• Default for Register 16, bit 10 is 0 (Loopback)
• Clarified Register 21, bit 10, Advanced LED Mode Configuration.
• Register 23 (Disconnect Counter) only applicable to 100 Mbps operation.
• Updated “Ordering Information” on page 4.
• Minor edits
• Minor edits
• Added clarification to RX_CLK throughout document, which is active only while LINK is established. See pin
PHYAD pins must be set to addresses other than 00h.
