Low Skew PCI / PCI-X Buffer
9112-27 Rev B 02/27/01
Pin Configuration
• Frequency range 0 - 140 MHz (3.3V)
• Less than 200 ps Jitter between outputs
• Skew controlled outputs < 100 ps
• Distribute one clock input to one bank of four
outputs
• 3.3V ±10% operation
• Available in 8 pin TSSOP, and SOIC packages.
The ICS9112-27 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.
The ICS9112-27 is characterized for operation from -40°C to
85°C for automotive and industrial applications.

Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. These ratings are
stress specifications only and functional operation of the device at these or any other conditions above those listed in the
operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended
periods may affect product reliability.
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.
