GENERAL DESCRIPTION
The ICS8701-01 is a low skew,
÷1, ÷2 LVCMOS/
LVTTL Clock Generator.
The low impedance
LVCMOS outputs are designed to drive 50
Ω series
or parallel terminated transmission lines. The effec-
tive fanout can be increased from 20 to 40 by utilizing
the ability of the outputs to drive two series 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 combi-
nation of ÷1 and ÷2 modes. The master reset/output enable input,
nMR/OE, resets the internal dividers and controls the active and
high impedance states of all outputs. The output polarity inputs,
INV0:1, control the polarity (inverting or non-inverting) of the out-
puts of each bank. Outputs QA0:QA4 are inverting for every com-
bination of the INV0:1 input. The timing relationship between the
inverting and non-inverting outputs at different frequencies is
shown in the Timing Diagrams.
The ICS8701-01 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
ICS8701-01 ideal for those clock distribution applications demand-
ing well defined performance and repeatability.
