REVISION HISTORY SHEET
Description of Change
Pin Description Table, revised Master Reset description.
Pin Description Table, pin 43 should be labeled at a PULL-UP instead of a
PULL-DOWN.
LVCMOS DC Characteristics table -in the I_IH and I_IL rows, FBDIV_SEL0 was
deleted from the "pulldown" row and was added to the "pullup" row.
Features section, changed max. output frequency from 200MHz to 183.3MHz,
and max. REF_CLK input frequency from 100MHz to 91.6MHz.
Control Function Table - revised Reference Frequency Range column and
Frequency columns to reflect the output frequency change.
AC Characteristics tables - changed Output Frequency from 200MHz max. to
183.3MHz max.
