Addendum to the SYM53C 860
Data Manual Version 2.0
December, 1997
This addendum contains new and changed information for the and SYM53C860 Data Manual
Version 2.0, published in June 1996. The information will be added to the next version of the
manual. The changes are listed in the order in which their appropriate chapters appear in the data
manual. The Power Management features of the SYM53C860E enable it to comply with
Microsoft’s PC 97 Hardware Design Guide. This addendum applies to both devices, SYM53C860
and SYM53C860E, except where noted.

Example:
SCLK= 80 MHz, SCF = 1(/1), XFERP = 0(/4),
CCF = 5(75.01-80.00MHz)
Synchronous send rate = (SCLK/SCF)/XFERP =
(80/1)/4=20MB/s
Synchronous receive rate = (SCLK/SCF)/4 =
(80/1)/4=20MB/s
