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 - 25MHz. The oscillator circuit is optimized for parallel resonant mode, and will require external capacitance
● Maximum output frequency up to 25MHz
● LVCMOS SEL0 and SEL1 inputs have internal pulldown resistors
● Part-to-part skew: 150ps (maximum)
● Propagation delay: 2ns (maximum)
● 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
GENERAL DESCRIPTION
The ICS85357-11 has 4 selectable crystal inputs. 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...
