PRELIMINARY
LVCMOS/LVTTL FANOUT BUFFER/DIVIDER
ICS87004I-03
GENERAL DESCRIPTION
FEATURES
The ICS87004I-03 is a low skew, ÷1, ÷2 ÷3, ÷4 ÷5,
• Two banks of two LVCMOS/LVTTL outputs,
ICS
HiPerClockS™
÷6 ÷8, ÷16 LVCMOS/LVTTL Fanout Buffer/Divider
and a member of theHiPerClockS™ family of High
Performance Clock Solutions from IDT. The
ICS87004I-03 has selectable clock inputs that
15Ω typical output impedance
• Selectable LVCMOS/LVTTL clock inputs
• LVCMOS_CLK supports the following input types: LVCMOS,
LVTTL
accept single ended input levels. Output enable pin controls
whether the output is in the active or high impedance state.
•
•
•
•
Maximum output frequency: 250MHz
Output skew: 40ps (typical)
Bank skew: 20ps (typical)
The ICS87004I-03 is characterized at 3.3V, 2.5V and mixed
3.3V/2.5V, 3.3V/1.8V, 2.5V/1.8V input/output supply operating
modes.Guaranteed bank, output, and part-to-part skew
characteristics make the ICS87004I-03 ideal for those
applications demanding well defined performance and
Part-to-part skew: TBD
