Si5386 Data Sheet
12-Channel, Any-Frequency, Any-Output wireless Jitter Attenu-
ator / Clock Multiplier with Ultra-Low Noise
The Si5386 is an ultra high performance wireless jitter attenuator with any frequency
outputs for eCPRI (ethernet-based Common Public Radio Interface) applications,
which demand the highest level of integration and phase noise performance. Based
on Silicon Laboratories’ 4th generation DSPLL technology, the Si5386 combines fre-
quency synthesis and jitter attenuation in a highly integrated digital solution with a
cost-effective oscillator, and without the need of any external loop filter components.
The fixed frequency oscillator 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.
eCPRI-based remote radio heads and fixed wireless systems require a diverse set of
clocks such as ADC/DAC, RF LOs, and Ethernet clocks. The Si5386 architecture is
designed to deliver high-performance JESD204B DCLK and SYSREF clock pairs
and flexible any-rate clocks for non-CPRI clocks such as Ethernet and system refer-
ence clocks all from a single IC.
Applications:
• Wireless Infrastructure
• eCPRI RRH (Remote Radio Head)
• BBU (Baseband Unit)
• Small Cell and μBTS
• DOCSIS
• Test and Measurement
