Summary of Changes
1.0
1/16/09
Data sheet created
1.1
10/13/09
Updated current consumption in Electrical Characteristics section.
Corrected data sheet omission of register 1 bit 8 for 1000Base-T Extended Status information.
Added the following register bits to provide further power saving during software power down: Tri-
state all digital I/Os (reg. 258.7), LDO disable (reg. 263.15), Low frequency oscillator mode (reg. 263.8).
Corrected tsu minimum for 1000Base-T in GMII Receive Timing Parameters table.
1.2
9/10/10
Added support for 2.5V VDD I/O.
Added LED drive current.
Updated KSZ9021GQ pin outs throughout data sheet to reflect pin out changes for silicon revision A3.
Updated boilerplate.
