HIGH FREQUENCY, LOW JITTER CLOCK OSCILLATOR ` FAST TURNAROUND CLOCK OSCILLATOR XCO FEATURES + DESCRIPTION The XCO clock series is a cutting edge family of low to high Fast Turnaround (Ships Within Days) frequency, low jitter output, single or multi - frequency clock oscillators. The XCO clocks are available in 7.0 x 5.0, 5.0 x 3.2, and Very Low Jitter (Typical 0.6 ps) 3.2 x 2.5 mm ceramic packages with output frequencies ranging 10 MHz to 1.2 GHz Frequency Range from 10 MHz to 1.2 GHz. Customer can select up to four output Selectable Single, Dual, or Quadruple Frequencies frequencies. Its outstanding flexibility significantly reduces design Stability as low as ±20 ppm (-40 ~ 85 °C) cycle time and overall cost. The XCO clock design incorporates a Available Sizes: low frequency crystal along with low jitter frequency synthesizer to provide a wide range of frequencies. The XCO clocks are available in LVCMOS, LVPECL and LVDS outputs, allowing for a wide variety of applications. 7.0 x 5.0 mm 5.0 x 3.2 mm 3.2 x 2.5 mm This product is ideal for the time conscious customer as shipments are made within days of a placed order.
