G. Castellini et al., 125 MHZ ECL DIGITAL OSCILLATOR SYNCHRONIZABLE BOTH IN FREQUENCY AND IN PHASE, IEEE transactions on instrumentation and measurement, 45(1), 1996, pp. 318-320
In this paper a 125 MHz digital oscillator with good frequency stabili
ty and instantaneous phase lock capability is presented, The circuit,
that was developed using the Motorola ''ECLPS'' and ''ECLPS lite'' log
ics, allows a frequency lock independent of the phase lock, which is a
feature not present in conventional PLL circuits.
