NOTICE - The following device(s) are recommended alternatives:

The 83918I is a low skew, 1:18 Crystal-to- LVCMOS/LVTTL Fanout Buffer. The 83918I has selectable LVCMOS/LVTTL clock or crystal inputs. The low impedance LVCMOS/LVTTL outputs are designed to drive 50Ω series or parallel terminated transmission lines. The 83918I is characterized at full 3.3V, full 2.5V and mixed 3.3V/2.5V, 3.3V/1.8V, and 2.5V/1.8V output operating supply modes. Guaranteed output and part-to-part skew characteristics make the 83918I ideal for those clock distribution applications demanding well defined performance and repeatability.

特性

  • Eighteen LVCMOS/LVTTL output
