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
  • 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/Output
    3.3V/3.3V
    3.3V/2.5V
    3.3V/1.8V
    2.5V/2.5V
    2.5V/1.8V
  • -40°C to 85°C ambient operating temperature
  • Available in lead-free (RoHS 6) package
