Sampling phase detector
Webthree times over-sampling phase detector in Fig. 4 synchronizes data to the rising edge of clock120, but generates control pulses with the rising edge of clock240. This phase detector would be modeled with a 120 degree, or one third of a clock cycle latency. Phase detector latency is an important parameter to model http://www.valjacksonassoc.com/REMEC/VAL%20DRO%20Section/Application%20Notes.pdf

WebApr 13, 2024 · Wireless communication at sea is an essential way to establish a smart ocean. In the communication system, however, signals are affected by the carrier frequency offset (CFO), which results from the Doppler effect and crystal frequency offset. The offset deteriorates the demodulation performance of the communication system. The … Webphase noise will generally track the multiplied reference phase noise, i.e. reference oscillator phase noise equals +20 log N +3 dB where N = (output freq/reference freq.). Outside the loop bandwidth, the phase noise will generally be that of the DRO. The phase noise near the region of the loop bandwidth will be affected by the loop gain/bandwidth.
