ESCRIPTION
The ICS8731-01 is a low voltage, low skew,
1-to-11 Differential-to-3.3V LVPECL Clock Multiplier/Zero
Delay Buffer. With output frequencies up to 700MHz the
ICS8731-01 is targeted at high performance clock
applications. Along with a fully integrated PLL the ICS8731-
01 contains frequency configurable, differential outputs
and external feedback inputs for multiplying clock
frequencies and regenerating clocks with “zero delay”.
Frequency multiplication is achieved by utilizing the
separate feedback and clock output dividers. The value of
the multiplier is determined by the ratio of the feedback
divider, M, to the output divider,N. For multiplier values
greater than 1, M must be greater than N. For multiplier
values less than 1,M must be less than N. The zero delay
mode is achieved with M and N at equal values. The divide
values of the clock and feedback outputs are controlled by
the DIV_SEL0:2 and FB_SEL0:1 inputs, respectively. The
ICS8731-01 accepts any differential signal and translates
it to differential 3.3V LVPECL output levels.
