ICS8701I
LOW SKEW,
÷1, ÷2
CLOCK GENERATOR
GENERAL DESCRIPTION
he ICS8701I is a low skew, ÷1, ÷2 Clock Gen-
erator and a member of the HiPerClockSfamily
of High Performance Clock Solutions from ICS.
The low impedance LVCMOS outputs are de-
signed to drive 50
Ω series or parallel terminated
transmission lines. The effective fanout can be increased from
20 to 40 by utilizing the ability of the outputs to drive two se-
ries terminated lines.
The divide select inputs, DIV_SELx, control the output
frequency of each bank. The outputs can be utilized in the ÷1,
÷2 or a combination of ÷1 and ÷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 controls the
active and high impedance states of all outputs.
The ICS8701I 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
ICS8701I ideal for those clock distribution applications de-
manding well defined performance and repeatability.
