GENERAL DESCRIPTION
The ICS83905 is a low skew, 1-to-6 LVCMOS / LVTTL Fanout Buffer and a member of the HiPerClockS™ family of High Performance Clock Solutions from IDT. The low impedance LVCMOS/LVTTL outputs are designed to drive 50Ω series or parallel terminated transmission lines. The effective fanout can be increased from 6 to 12 by utilizing the ability of the outputs to drive two series terminated lines.

FEATURES
• Six 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:
