ICS9112-27 Low Skew PCI / PCI-X Buffer General Description Features The ICS9112-27 is a high performance, low skew, low jitter Frequency range 0 - 140 MHz (3.3V) PCI / PCI-X clock driver. It is designed to distribute high Less than 200 ps Jitter between outputs speed signals in PCI / PCI-X applications operating at Skew controlled outputs < 100 ps speeds from 0 to 140 MHz. Distribute one clock input to one bank of four outputs The ICS9112-27 is characterized for operation from -40C 3.3V 10% operation to 85C for automotive and industrial applications. Available in 8 pin TSSOP, and SOIC packages.

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.
