ICS839893I

LOW SKEW, 1-TO-13

LVCMOS/LVTTL BUFFER DIVIDER

GENERAL DESCRIPTION

The ICS839893I is a high-performance one to

thirteen LVCMOS/LVTTL buffer/divider and is

a member of the HiPerClockS™ family of High

Performance Clock Solutions from ICS. The

device has two selectable LVCMOS/LVTTL

clock inputs and it generates 13 new LVCMOS/LVTTL clock

outputs. The first bank of six outputs offers divide-by-1, 2, 4,

8 or 16. The second bank of six outputs can be configured to

the same divide ratio as the first bank, or with an additional

divide-by-two. The first two banks can be placed into a high-

impedance output state with the assertion of a LOW on the

nOE/MR input. One additional output can be configured

to divide-by-4, 6, 8 or 16. This device is functional with full

3.3V or full 2.5V supplies.
