ESCRIPTION
The ICS8701 is a low skew, 梅1, 梅2 Clock Gen-
erator and a member of the HiPerClockS鈩?/div>
HiPerClockS鈩?/div>
family of High Performance Clock Solutions
from ICS. The low impedance LVCMOS out-
puts are designed to drive 50鈩?series or par-
allel terminated transmission lines. The effective fanout can
be increased from 20 to 40 by utilizing the ability of the
outputs to drive two series terminated lines.
,&6
The divide select inputs, DIV_SELx, control the output fre-
quency of each bank. The outputs can be utilized in the 梅1,
梅2 or a combination of 梅1 and 梅2 modes. The bank enable
inputs, BANK_EN0:1, support enabling and disabling each
bank of outputs individually. The master reset input, nMR/
OE, resets the internal frequency dividers and also con-
trols the active and high impedance states of all outputs.
The ICS8701 is characterized at 3.3V and mixed 3.3V input
supply, and 2.5V output supply operating modes. Guaranteed
bank, output and part-to-part skew characteristics make the
ICS8701 ideal for those clock distribution applications de-
manding well defined performance and repeatability.
