G ENERAL D ESCRIPTION

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.

I NPUTS :

CLK I NPUT :

For applications not requiring the use of the test clock, it can be left floating. Though not required, but for additional protection, a 1k Ω resister can be tied from the CLK input to ground.C ONTROL P INS :

All control pins have internal pull-ups and pull-downs;additional resistance is not required but can be added for additional protection. A 1k Ω resister can be used.

R ECOMMENDATIONS FOR U NUSED I NPUT AND O UTPUT P INS

O UTPUTS :LVCMOS O UTPUT :

All unused LVCMOS output can be left floating. We recommend that there is no trace attached.
