(2/2005)
In Chapter 2 Table 30 on page 60 was revised to make note of required termination
circuits.
In Chapter 3 Table 37 on page 76, Table 40 on page 79, and Table 41 on page 84 were
revised to document support for an operating frequency of 300Mhz.

06
• Chapter 2, added the signal type to both the PCLK and PGNTX signals in the PCI
Signals section.
• Chapter 1, 2, and 3, added a note about the External Mode.
05
• Chapter 3, OC-12 timing specifications section, Tc12o modified to allow a greater
variety of phy components. The maximum value is consistent with previously
specified 10.0ns value.
• Corrected revision history.
04
• Chapter 2, corrected OC-3, CPn_3 signal I/O type from O_PU to I_PU.
• Chapter 2, corrected JTAG identification code part number binary value.
• Chapter 2, clarified the function of the QACLKI signal for Internal Mode.
03
• Not released.
02
• Reflects the specification change of the V_DD Supply Voltage from 1.2V to 1.25V.
• Chapter 3, modified power sequencing information, added I_DDT and I_DDF values.
• Chapter 4, modified keep out zone information.
01
• Includes updates from C-5e silicon A1 to B0 from C5ENPA1-DS Data Sheet.
Specifically, fifteen (15) maximum timing specifications were changed:
• For BMU: Tmco went from 3.4 to 3.5, Tmao went from 3.4 to 3.7, and Tmdo Tmdz,
Tmdv went from 4.0 to 4.4.
• For TLU: Ttco went from 3.4 to 4.0, Ttao went from 3.4 to 3.9, and Ttdo, Ttdz Ttdv
went from 3.7 to 4.5.
• For QMU SRAM (Internal Mode): Tqco went from 3.4 to 3.9, Tqao went from 3.4 to
3.7, and Tqdo, Tqdz, Tqdv went from 3.4 to 4.0. Also, Tqc minimum value changed
from 5.7 to 6.25 with QMU on-board memory and to 6.67 with QMU memory
daughter board.
