    General Description  
    Product Features  
    The PT7V2727/3727 are low-cost, high-performance 3.3V/5.0v  
    VCXO, designed to replace expensive VCXO modules.  
    The on-chip voltage causes clocks to vary by ±120ppm.  
    They use an inexpensive external pullable crystal at  
    27MHz to produce the same output frequency.
