ICS873990 - LOW VOLTAGE LVCMOS/ CRYSTAL-TO-LVPECL/ECL CLOCK GENERATOR

General Description

The ICS873990 is a low voltage, low skew, 3.3V LVPECL/ECL Clock Generator and a member HiPerClockS™ of the HiPerClockS™ family of High Performance Clock Solutions from ICS.

The ICS873990 has two selectable clock inputs.

Key Features

  • 14 differential LVPECL outputs.
  • Selectable crystal oscillator interface or TEST_CLK inputs.
  • TEST_CLK accepts the following input levels: LVCMOS, LVTTL.
  • Output frequency: 400MHz (maximum).
  • Crystal input frequency range: 10MHz to 25MHz.
  • VCO range: 200MHz to 800MHz.
  • Output skew: 250ps (maximum).
  • Cycle-to-cyle jitter: ±50ps (typical).
  • LVPECL mode operating voltage supply range: VCC = 3.135V to 3.465V, VEE = 0V.
