Systems, Inc.
4:1, SINGLE-ENDED MULTIPLEXER
GENERAL DESCRIPTION
FEATURES
The ICS83054I is a low skew, 4:1, Singleended Multiplexer and a member of the
HiPerClockS™ HiPerClockS ™ family of High Performance
Clock Solutions from ICS. The ICS83054I
has four selectable single-ended clock inputs
and one single-ended clock output. The output has a
VDDO pin which may be set at 3.3V, 2.5V, or 1.8V, making
the device ideal for use in voltage translation applications.
An output enable pin places the output in a high
impedance state which may be useful for testing or
debug. The device operates up to 250MHz and is packaged in a 16 TSSOP.
• 4:1 single-ended multiplexer
ICS
• Q nominal output impedance: 7Ω (VDDO =3 .3V)
• Maximum output frequency: 250MHz
• Propagation delay: 3ns (maximum), VDD = VDDO = 3.3V
• Input skew: 225ps (maximum), VDD = VDDO = 3.3V
• Part-to-part skew: 475ps (maximum), VDD = VDDO = 3.3V
• Operating supply modes:
VDD/VDDO
3.3V/3.3V
3.3V/2.5V
3.3V/1.8V
2.5V/2.5V
2.5V/1.8V
• -40°C to 85°C ambient operating temperature
• Available in both standard and lead-free RoHS-compliant
packages

APPLICATION INFORMATION
RECOMMENDATIONS FOR UNUSED INPUT PINS
INPUTS:
CLK INPUT:
For applications not requiring the use of a clock input, it can
be left floating. Though not required, but for additional
protection, a 1kΩ resistor can be tied from the CLK input to
ground.
83054AGI
LVCMOS CONTROL PINS:
All control pins have internal pull-ups or pull-downs;
additional resistance is not required but can be added for
additional protection. A 1kΩ resistor can be used.
