High Quality LC-PLLs

Silicon Creations provides precise, ultra-low jitter LC-tank based PLLs for demanding applications such as AFE, Converter, high-end PHY and RF clocking. Our LC-PLL portfolio includes: 

• Advanced Fractional-N LC-PLLs with all digital architecture supporting an LC-Tank are proven in 7nm FinFET and commencing production. These IPs are low power (below 10mW), small (below 0.1mm2) and can provide broadband jitter comfortably below 300fs RMS.
• 28nm Fractional-N synthesizers in production in TSMC, UMC and SMIC with generated LTJ below 500fs RMS broadband and below 150fs RMS integrated above 1MHz.

•  Wideband integrated jitter <400fs in integer mode, <800fs in fractional mode with high-speed / clean reference with active fractional noise cancellation
•  Passes PCIe6 reference clock requirements with wide margin
•  Reference spur <200fs RMS
•  Random period jitter <30fs RMS
•  Low-leakage standby mode for fast re-locking
  •  “Instant” frequency lock from standby
  •  < 0.1% frequency error over PVT for open-loop DCO
•  ±8% frequency tuning range
•  Programmable loop bandwidth

• Saves power and system cost:
• Replaces expensive (>$10) external jitter cleaner PLL chips requiring off-chip differential buffers and receivers with silicon area costing just a few cents.
• Reduces risk.

• Clock de-spreading for Video format converters.
• Jitter cleaning for Synchronous Ethernet and Gapped Clock cleaning in OTU systems

• Synthesizable RTL (Verilog)
• Timing constraints
• Documentation
• Comprehensive support
