4:1 OR 2:1, CRYSTAL OSCILLATOR-TO-3.3V LVPECL / ECL MULTIPLEXER
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.
