FOS_CTL
I
3-Level
Frequency Offset Control.
This pin enables or disables use of the CKIN2 FOS reference
as an input to the clock selection state machine.
L = FOS Disabled.
M = Stratum 3/3E FOS Threshold.
H = SONET Minimum Clock FOS Threshold.
This pin has both weak pull-ups and weak pull-downs and
defaults to M. Some designs may require an external resistor
voltage divider when driven by an active device that will tri-
state.

C1A
O
LVCMOS
CKIN1 Active Clock Indicator.
This pin serves as the CKIN1 active clock indicator.
0 = CKIN1 is not the active input clock.
1 = CKIN1 is currently the active input clock to the PLL.
59
C2A
O
LVCMOS
CKIN2 Active Clock Indicator.
This pin serves as the CKIN2 active clock indicator.
0 = CKIN2 is not the active input clock.
1 = CKIN2 is currently the active input clock to the PLL.

BWSEL0
BWSEL1
I
3-Level
Bandwidth Select.
These pins are three level inputs that select the DSPLL closed
loop bandwidth. Detailed operations and timing characteristics
for these pins may be found in the Any-Frequency Precision
Clock Family Reference Manual.
These pins have both weak pull-ups and weak pull-downs and
default to M. Some designs may require an external resistor
voltage divider when driven by an active device that will tri-
state.

DIV34_0
DIV34_1
I
3-Level
CKOUT3 and CKOUT4 Divider Control.
These pins control the division of CKOUT3 and CKOUT4 rela-
tive to the CKOUT2 output frequency. Detailed operations and
timing characteristics for these pins may be found in the Any-
Frequency Precision Clock Family Reference Manual.
These pins have both weak pull-ups and weak pull-downs and
default to M. Some designs may require an external resistor
voltage divider when driven by an active device that will tri-
state.

FRQSEL0
FRQSEL1
FRQSEL2
FRQSEL3
I
3-Level
Multiplier Select.
These pins are three level inputs that select the input clock and
clock multiplication setting according to the Any-Frequency
Precision Clock Family Reference Manual, depending on the
FRQTBL setting.
These pins have both weak pull-ups and weak pull-downs and
default to M. Some designs may require an external resistor
voltage divider when driven by an active device that will tri-
state.

CKOUT3+
CKOUT3–
OMULTI
Clock Output 3.
Differential output clock with a frequency specified by FRQSEL
and FRQTBL settings. Output is differential for LVPECL, LVDS,
and CML compatible modes. For CMOS format, both output
pins drive identical single-ended clock outputs.
