ICS87946I-147
DATASHEET
General Description
Features
The ICS87946I-147 is a low skew, ÷1, ÷2 LVCMOS/LVTTL Clock
Generator. The ICS87946I-147 has two selectable single ended
clock inputs. The single ended clock inputs accept LVCMOS or
LVTTL input levels. The low impedance LVCMOS/LVTTL outputs are
designed to drive 50 series or parallel terminated transmission
lines. The effective fanout can be increased from 10 to 20 by utilizing
the ability of the outputs to drive two series terminated lines.
• Ten single ended LVCMOS/LVTTL outputs,
7 typical output impedance
• Selectable LVCMOS/LVTTL CLK0 and CLK1 inputs
• CLK0 and CLK1 can accept the following input levels:
LVCMOS and LVTTL
• Maximum input frequency: 250MHz
• Bank skew: 30ps (maximum)
The divide select inputs, DIV_SELx, control the output frequency of
each bank. The outputs can be utilized in the ÷1, ÷2 or a
combination of ÷1 and ÷2 modes. The master reset input, MR/nOE,
resets the internal frequency dividers and also controls the active
and high impedance states of all outputs.
• Output skew: 175ps (maximum)
• Part-to-part skew: 850ps (maximum)
• Multiple frequency skew: 200ps (maximum)
• 3.3V core, 3.3V or 2.5V output supply modes
• -40°C to 85°C ambient operating temperature
• Lead-free packaging
The ICS87946I-147 is characterized at full 3.3V for input VDD, and
mixed 3.3V and 2.5V for output operating supply mode. Guaranteed
bank, output and part-to-part skew characteristics make the
ICS87946I-147 ideal for those clock distribution applications
demanding well defined performance and repeatability.

Recommendations for Unused Input and Output Pins
Inputs:
OUTputs:
LVCMOS Control Pins
LVCMOS Outputs
All control pins have internal pulldowns; additional resistance is not
required but can be added for additional protection. A 1k resistor
can be used.
All unused LVCMOS output can be left floating. There should be no
trace attached.
CLK Inputs
For applications not requiring the use of a clock input, it can be left
floating. Though not required, but for additional protection, a 1k
resistor can be tied from the CLK input to ground.
