ICS83905I - 1:6 CRYSTAL INTERFACE-TO LVCMOS/LVTTL FANOUT BUFFER

Datasheet Summary

Description

The ICS83905I is a low skew, 1-to-6 LVCMOS / LVTTL Fanout Buffer and a member of the HiPerClockS™ HiPerClockS™ family of High Performance Clock Solutions from ICS.

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

Features

  • 6 LVCMOS / LVTTL outputs.
  • Outputs able to drive 12 series terminated lines.
  • Crystal oscillator interface.
  • Crystal input frequency range: 10MHz to 40MHz.
  • Output skew: 80ps (maximum).
  • RMS phase jitter @ 25MHz, (100Hz - 1MHz): 0.26ps (typical) (VDD = VDDO = 2.5V) Phase noise: Offset Noise Power 100Hz -129.7 dBc/Hz 1kHz -144.4 dBc/Hz 10kHz -147.3 dBc/Hz 100kHz -157.3 dBc/Hz.
  • 5V tolerant enable inputs.
  • Synchronous output ena.
