자주 묻는 질문(FAQ)
What is a clock jitter cleaner, and how does the LMK03806BISQE/NOPB work?
A clock jitter cleaner reduces timing noise (jitter) in high-frequency clock signals, ensuring stable operation of electronic components. The LMK03806BISQE/NOPB uses dual PLLs to lock onto an input clock (10MHz?C3GHz), filter out noise, and output clean, synchronized signals. This ensures transceivers, processors, and memory operate in perfect harmony, critical for high-speed data transfer in 400G systems.
Why is 150fs jitter important for high-speed optical transceivers?
150fs jitter is 10x lower than the 1.5ps threshold for 400G optical transceivers, ensuring signal edges remain sharp and bits don??t overlap. Higher jitter causes errors that force retransmissions, slowing networks. This ultra-low jitter enables transceivers to maintain reliable links over longer distances, reducing operational costs for data centers and telecom providers.
How does the BGA package benefit dense PCB designs?
The BGA package??s small footprint and high pin count fit into ultra-dense PCBs like 400G transceiver modules, where space is limited by lasers and detectors. Its solder ball connections improve thermal conductivity, handling the power density of high-frequency operation. This design also enables automated assembly, critical for high-volume production of compact, high-performance systems.
What role do dual PLLs play in the LMK03806BISQE/NOPB?
Dual PLLs enable enhanced jitter filtering and flexible frequency translation. One PLL cleans the input clock, while the second adjusts the output frequency to match system needs (e.g., converting 100MHz to 1GHz). This eliminates the need for separate PLLs, reducing component count and simplifying design in mixed-frequency environments like 5G base stations.
How does this jitter cleaner support future high-speed standards?
With a 3GHz maximum input frequency and 8 configurable outputs, it supports next-gen 800G Ethernet and beyond??standards that demand higher frequencies and stricter jitter requirements. Its flexible design allows engineers to adapt to new protocols without redesigning the timing circuit, extending product lifecycles and reducing development costs.
