GENERAL DESCRIPTION
The ICS85357-11 is a 4:1 or 2:1, Crystal Oscillator-to-3.3V LVPECL / ECL Multiplexer and is a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. The ICS85357-11 has 4 selectable crystal inputs.

FEATURES
• 1 differential 3.3V LVPECL output
• 4:1 or 2:1 Crystal Oscillator Multiplexer
• Supports parallel resonant crystals with a frequency range
   of 10MHz to 27MHz. The oscillator circuit is optimized for
   parallel resonant mode, and will require external capacitance
• Maximum output frequency: 27MHz
• LVCMOS/LVTTL SEL0 and SEL1 inputs have
   internal pulldown resistors
• LVPECL mode operating voltage supply range:
   VCC = 3.135V to 3.465V, VEE = 0V
• ECL mode operating voltage supply range:
   VCC = 0V, VEE = -3.135V to -3.465V
• 0°C to 70°C ambient operating temperature
• Industrial temperature information available upon request
