ICS8725-01
1:5 DIFFERENTIAL-TO-HSTL
ZERO DELAY CLOCK GENERATOR
GENERAL DESCRIPTION
The ICS8725-01 is a highly versatile 1:5 Dif-
ferential-to-HSTL clock generator and a
member of the HiPerClockS family of High
Performance Clock Solutions from ICS. The
ICS8725-01 has a fully integrated PLL and can
be configured as zero delay buffer, multiplier or divider,
and has an output frequency range of 31.25MHz to
700MHz. The reference divider, feedback divider and out-
put divider are each programmable, thereby allowing for
the following output-to-input frequency ratios: 8:1, 4:1, 2:1,
1:1, 1:2, 1:4, 1:8. The external feedback allows the device
to achieve “zero delay” between the input clock and the
output clocks. The PLL_SEL pin can be used to bypass the
PLL for system test and debug purposes. In bypass mode,
the reference clock is routed around the PLL and into the
internal output dividers.
