83918 - 1:18 Crystal-to-LVCMOS/LVTTL Fanout Buffer

Datasheet Summary

Description

The 83918 is a low skew, 1:18 Crystal-to- LVCMOS/LVTTL Fanout Buffer.

The 83918 has selectable LVCMOS/LVTTL clock or crystal inputs.

The low impedance LVCMOS/LVTTL outputs are designed to drive 50 series or parallel terminated transmission lines.

Features

  • Eighteen LVCMOS/LVTTL output.
  • Selectable crystal oscillator interface or LVCMOS_CLK.
  • Maximum output frequency: 200MHz.
  • Crystal input frequency range: 10MHz to 40MHz.
  • RMS phase jitter using a 25MHz crystal (1kHz.
  • 1MHz): 0.449ps (typical) @ 3.3V/3.3V.
  • Output skew: 75ps (maximum) @ 3.3V/3.3V.
  • Operating supply modes: Core/Ou.

Low Skew, 1:18 Crystal-to-LVCMOS/LVTTL Fanout Buffer 83918 Data Sheet General Description The 83918 is a low skew, 1:18 Crystal-to- LVCMOS/LVTTL Fanout Buffer. The 83918 has selectable LVCMOS/LVTTL clock or crystal inputs. The low impedance LVCMOS/LVTTL outputs are designed to drive 50 series or parallel terminated transmission lines. The 83918 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 83918 ideal for those clock distribution applications demanding well defined performance and repeatability.
