    Function
    1
    OPOUT
    Op-Amp Output
    2
    OPN
    Op-Amp Negative Input
    3
    PHO
    Phase detector output
    4
    LOSIN
    INPUT (Used with LOS)
    Logic 0, VCXO control voltage is enabled.
    Logic 1, VCXO control voltage (pin 16) is disabled and OUT1 and OUT2 are within +/-75 ppm
    of center frequency
    Has Internal pull-down resistor
    5
    DATAIN
    Phase detector Input signal (TTL switching thresholds)
    6
    CLKIN
    Phase detector Clock signal (TTL switching thresholds)
    7
    GND
    Cover and Electrical Ground
    8
    LOS
    OUTPUT (Used with LOSIN)
    Logic 1 if there are no transitions detected at DATAIN after 256 clock cycles at CLKIN. As soon
    as a transition occurs at DATAIN, LOS is set to a logic low.
    Logic 0 = Input frequency detected
