Op-Amp Negative Input
Phase detector Output
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
Phase detector Input signal (TTL switching thresholds)
Phase detector Clock signal (TTL switching thresholds)
Cover and Electrical Ground
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
Recovered Clock
Recovered Data
Divided-down VCXO Output, or Disabled
INPUT
Logic 0, OUT1, OUT2, RCLK, RDATA are set to a high impedance state.
Logic 1, OUT1, OUT2, RCLK, RDATA are active.
