资 源 简 介
The Si5380 is a high performance， integer-based （M/N） clock generator for small cell applicaTIons which demand the highest level of integraTIon and phase noise performance. Based on Silicon Laboratories’ 4th generaTIon DSPLL technology， the Si5380 combines frequency synthesis and jitter attenuaTIon in a highly integrated digital solution that eliminates the need for external VCXO and loop filter components. A low cost， fixed-frequency crystal provides frequency stability for free-run and holdover modes. This all-digital solution provides superior performance that is highly immune to external board disturbances such as power supply noise.。
Applications • JESD204B clock generation • Remote Radio Units （RRU）， Remote Access Networks （RAN）， picocells， small cells • Wireless base stations （3G， GSM， W-CDMA， 4G/LTE， LTE-A） • Remote Radio Head （RRH）， wireless repeaters， wireless backhaul • Data conversion sampling clocks （ADC， DAC， DDC， DUC）
