The 85357-11 is a 4:1 or 2:1, Crystal Oscillator-to-3.3V LVPECL / ECL Multiplexer . The 85357-11 has 4 selectable crystal inputs. The device can support 10MHz to 27MHz parallel resonant crystals by connecting external capacitors between XTALIN/XTALOUT and ground. The select pins have internal pulldown resistors and leaving one input unconnected (pulled to logic low by the internal resistor) will transform the device into a 2:1 multiplexer. The SEL1 lead is the most significant line and the binary number applied to the select pins will select the same numbered data input (i.e., 00 selects XTALIN0/XTALOUT0).

Features

  • One 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
  • Available in lead-free (RoHS 6) package
