The frequency detector according to at least one phase relationship between the first clock and the second clock and the input data, generating a second control signal. 检验电路根据该第二控制信号,来判断是否调整第一时钟及第二时钟的频率. Test circuit according to the second control signal, to ...
The pull-in range,\pm \Delta \omega_P, is defined as the range of input frequencies that the DPLL will lock to. If the center frequency of the DPLL is 10 MHz and the pull-in range is 1 MHz, the DPLL will lock on an input frequency from 9 to 11 MHz in a time TP (assuming N...
A sequential phase-frequency detector circuit using precharged logic and a minimum number of transistors is suitable for use in a delay locked loop because of insensitivity to a stuck delay line output signal. The detector receives standard REFERENCE and LOCAL input signals and provides UP and ...

A phase/frequency detector, especially for VHF/UHF synthesisers, for modulators and for other ICs where an "in-lock" signal is required, provides a novel output signal for phase lock detection. The detector has two inputs (REF,N) to which signals of different phase are applied, gating mean...

The first essential element in this circuit is the phase frequency detector (PFD). The PFD compares the frequency and phase of the input to REFIN to the frequency and phase of the feedback to RFIN. The ADF4002 is a PLL that can be configured as a standalone PFD (with the feedback di...
