Si5381/82 Data Sheet

Multi-DSPLL Wireless Jitter Attenuator / Clock Multiplier with

Ultra-Low Noise

The Si5381/82 is an ultra high performance wireless jitter attenuator with multiple

DSPLLs, optimized for wireless BBU (Baseband Unit) and DU (Distribution Unit) ap-

plications. The industry’s first multi-PLL wireless jitter attenuator device is capable of

replacing multiple discrete, high performance, VCXO-based jitter attenuators with a

fully integrated single chip solution. The featured multi-PLL architecture supports in-

dependent timing paths for Ethernet and CPRI (Common Public Radio Interface)

clock cleaning , and generates any low-jitter, general-purpose clocks. The fixed fre-

quency 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.

Applications:

• Wireless Infrastructure

• eCPRI RRH (Remote Radio Head)

• BBU (Baseband Unit)

• DU (Distribution Unit)

• Test and Measurement

54 MHz

OSC
