The invention discloses a method for adjusting a low-frequency oscillator clock period by utilizing a crystal oscillator clock. The method comprises the steps of performing coarse adjustment on the frequency of a low-frequency oscillator according to the bit width of a control signal for controlling...
已知时钟频率f=3.5GHz,因为1GHz=109Hz,所以将3.5GHz换算为Hz可得:3.5GHz=3.5×109Hz。根据周期和频率的关系T=f1,把f=3.5×109Hz代入公式,可得T=3.5×1091s。计算3.5×1091≈0.286×10−9s。又因为1s=106μs,将0.286×10−9s换算为μs,即0.286×10−9×106μs=0.286×10−3μs=0.286ns(1ns=10...
The problem can be solved by increasing the clock period or by redesigning the combinational logic to have a shorter propagation delay. Hold Time Constraint The register R2 in Figure 3.38(a) also has a hold time constraint. Its input, D2, must not change until some time, thold, after the...
(0 ppm error) Very low power consumption Highly linear VCXO Adjustable output delay Optional clock input (CLKIN) Available in three packages types: Low output period jitter: < 70 ps pp, typ Configurable spread spectrum selectable at each output Operates ...
The method involves measuring periods of the network frequency clock signal (CL1) using a measuring frequency derived from a quartz oscillator frequency. The network frequency is used to generate the frequency of the clock signal, if the measured period of the network frequency clock signal lies ...
The clock frequency controller is further configured to receive a request from the processor for a target number of processor instructions to be handled in a particular time period. The clock frequency controller is further configured to output a frequency control signal to the clock generator for ...
The correct choice is to use a Hardware Timer with Interrupt to call your function.These hardware timers, using interrupt, still work even if other functions are blocking. Moreover, they are much more precise (certainly depending on clock frequency accuracy) than other software timers using ...
