ICS2304NZ-1
LOW SKEW PCI/PCI-X BUFFER
Description
Features
The ICS2304NZ-1 is a high-performance, low skew,
low jitter PCI/PCI-X clock driver. It is designed to
distribute high-speed signals in PCI/PCI-X applications
operating at speeds from 0 to 140 MHz.
• Packaged in 8-pin TSSOP (4.4 mm body)
• Available in Pb (lead) free package
• Frequency range of 0 to 140 MHz
• Less than 100 ps skew between outputs
• Distribute one clock input to one bank of four outputs
• Operating voltage of 3.3 V 10%
The ICS2304NZ-1 is characterized for operation from
-40°C to +85°C for automotive and industrial
applications.
• Available in commercial and industrial temperature
ranges

Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the ICS2304NZ-1. These ratings,
which are standard values for ICS commercially rated parts, are stress ratings only. Functional operation of
the device at these or any other conditions above those indicated in the operational sections of the
specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can
affect product reliability. Electrical parameters are guaranteed only over the recommended operating
temperature range.

Notes:
1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current
ratings are observed.
2. This value is limited to 4.6 V maximum.
3. The package thermal impedance is calculated in accordance with JESD 51.
