FPGA IMPLEMENTATION OF PHASE LOCKED LOOP (PLL) WITH SYNCHRONOUS RESET

WebbA reset signal generation circuit of the present invention includes a phase locked loop (PLL) selector, a plurality of PLLs, a locking detector, a clock selector, a counter, and a reset synchronizer. The PLL selector is activated when an external reset signal is high and provides a signal for selecting one of the plurality of PLLs according to a power down … Webbsignals. PLL Behavior • PLL lock time —Also known as the PLL acquisition time, PLL lock time is the amount of time required by the PLL to attain the target frequency and phase relationship after power-up, after a programmed output frequency change, or after a reset of the PLL. Simulation software does not model a realistic PLL lock time. bure za vino

WebbHave a four bit counter that resets whenever the signal changes, then sample and process data when the counter is at eight. Or generate an intermediate clock: Set to 0 when counter is reset or zero, set to 1 when counter is at eight. Use this to feed a PLL (see about phase alignment!), and sample data at rising flank. Webbare clocked by REF. LCount resets to zero when it reaches its maximum count (i.e. 512 for the 5T2010) or if there is a cycle for which Δφ > tlock φ. ULWindow resets when it reaches its maximum count (i.e. 256 for 5T2010). ULCount resets when ULWindow resets.
