ESCRIPTION
The ICS8705 is a highly versatile 1:8 Differen-
tial-to-LVCMOS/LVTTL Clock Generator and a
member of the
HiPerClockS amily of High Per-
formance Clock Solutions from ICS. The ICS8705
has two selectable clock inputs. The CLK1,
nCLK1 pair can accept most standard differential input lev-
els. The single ended CLK0 input accepts LVCMOS or LVTTL
input levels.The ICS8705 has a fully integrated PLL and can
be configured as zero delay buffer, multiplier or divider and
has an input and output frequency range of 15.625MHz to
250MHz. The reference divider, feedback divider and output
divider are each programmable, thereby allowing for the fol-
lowing 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.
