Below is a list of independent functions, which can be
assigned to each of the four S1 and S2 combinations. When
a particular S1 and S2 combination is selected, the device will
assume the configuration (which is essentially a set of
functions given in
Table 2
, below) that has been preassigned
to that particular combination.
Inv CLKB4
Generates an inverted clock on the CLKB4 output. When this option is
programmed, CLKB4 and CLKB5 will become complimentary pairs.
Enables/Disables internal pulldowns on all outputs
Enables/Disables internal pulldowns on the feedback path (applicable to both
internal and external feedback topologies)
Selects between the internal and the external feedback topologies

Auto Power-down Enable Enables/Disables the auto power down circuit, which monitors the reference clock rising
edges and shuts down the device in case of a reference “failure.” This failure is triggered
by a drift in reference frequency below a set limit. This auto power down circuit is
disabled internally when one or more of the outputs are configured to be driven directly
from the reference clock.
PLL Power-down
Shuts down the PLL when the device is configured as a non-PLL fanout buffer.
M[7:0]
Assigns an eight-bit value to reference divider –M. The divider can be any integer value
from 1 to 256; however, the PLL input frequency cannot be lower than 10 MHz.
N[7:0]
Assigns an eight-bit value to feedback divider –N. The divider can be any integer value
from 1 to 256; however, the PLL input frequency cannot be lower than 10 MHz.
X[6:0]
Assigns a seven-bit value to output divider –X. The divider can be any integer value
from 5 to 130. Divide by 1,2,3, and 4 are preprogrammed on the device and can be
activated by the appropriate output mux setting.
Divider Source
Selects between the PLL output and the reference clock as the source clock for the
output dividers.
CLKA54 Source
Independently selects one out of the eight possible output dividers that will connect to
the CLKA5 and CLKA4 pair. Please refer to
Table 3
for a list of divider values.
CLKA32 Source
Independently selects one out of the eight possible output dividers that will connect to
the CLKA3 and CLKA2 pair. Please refer to
Table 3
for a list of divider values.
CLKA10 Source
Independently selects one out of the eight possible output dividers that will connect to
the CLKA1 and CLKA0 pair. Please refer to
Table 3
for a list of divider values.
CLKB54 Source
Independently selects one out of the eight possible output dividers that will connect to
the CLKB5 and CLKB4 pair. Please refer to
Table 3
for a list of divider values.
CLKB32 Source
Independently selects one out of the eight possible output dividers that will connect to
the CLKB3 and CLKB2 pair. Please refer to
Table 3
for a list of divider values.
CLKB10 Source
Independently selects one out of the eight possible output dividers that will connect to
the CLKB1 and CLKB0 pair. Please refer to
