Multi-Function Input.
This pin functions as a multi-function input pin. The pin function (OEB_all, OEB_01,
OEB_23, OEB_45, OEB_67, or Reset) is user-selectable at time of configuration using
the ClockBuilder configuration utility. A resistor voltage divider is recommended when
controlled by a signal greater than 1.2 V. See “2. Typical Application Circuit” for details.
Multi-Function Input.
This pin functions as a multi-function input pin. The pin function (OEB_all, OEB_01,
OEB_23, OEB_45, OEB_67, or Reset) is user-selectable at time of configuration using
the ClockBuilder configuration utility. A resistor voltage divider is recommended when
controlled by a signal greater than 1.2 V. See “2. Typical Application Circuit” for details.
The device operates from a 1.8, 2.5, or 3.3 V supply. A 0.1 μF bypass capacitor should
be located very close to this pin.
Loss of Signal.
This pin functions as an input clock loss of signal status pin.
0 = no loss of signal
1 = loss of signal present
This pin is open drain and requires an external >1 k  pullup resistor.
Output Clock 7.
CMOS output clock. If unused, this pin must be left floating.
Output Clock 6.
CMOS output clock. If unused, this pin must be left floating.
Power supply for clock outputs 6 and 7. May be operated from a 1.8, 2.5, or 3.3 V sup-
ply. A 0.1 μF bypass capacitor should be located very close to this pin. If CLK6/7 are not
used, this pin must be tied to pin 7 and/or pin 24.
Multi-Function Input.
This pin functions as a multi-function input pin. The pin function (OEB_all, OEB_01,
OEB_23, OEB_45, OEB_67, Frequency Select, or Reset) is user-selectable at time of
configuration using the ClockBuilder configuration utility
Output Clock 5.
CMOS output clock. If unused, this pin must be left floating.
Output Clock 4.
CMOS output clock. If unused, this pin must be left floating.
Power supply for clock outputs 4 and 5. May be operated from a 1.8, 2.5 or 3.3 V sup-
ply. A 0.1 μF bypass capacitor should be located very close to this pin. If CLK4/5 are not
used, this pin must be tied to pin 7 and/or pin 24.
Power supply for clock outputs 2 and 3. May be operated from a 1.8, 2.5, or 3.3 V sup-
ply. A 0.1 μF bypass capacitor should be located very close to this pin. If CLK2/3 are not
used, this pin must be tied to pin 7 and/or pin 24.
Output Clock 3.
CMOS output clock. If unused, this pin must be left floating.
