Clock solutions for Xilinx FPGAs

With the continued increase in clock rate and integration of high speed SerDes in FPGAs, the need for high performance and flexible clocking becomes ever so critical. Today's FPGAs need to support high speed data transmission in excess of 20 Gbps per lane and core clock rates of over 1 GHz, which significantly reduces the timing error margin for clocks.

TI can meet these demands with a full portfolio of low noise clock jitter cleaners, generators and buffers as well as offering a range of software-programmable, EEPROM or pin-mode configurable clocks that deliver a great level of flexibility for almost any application environment.

Key portfolio highlights:

  • Clock buffers ranging from ultra-low noise to low power
    • Lowest additive noise with <25 fs RMS
    • Pin-programmable outputs for ultimate flexibility
  • Clock generators for replacing crystals and oscillators
    • Industry's lowest jitter with 100 fs RMS satisfies stringent protocols (10GbE, XAUII, FC, SATA/SAS, etc.)
    • Low power multi-PLL clocks for consumer and industrial applications
  • Clock jitter cleaners/attenuators to maximize performance
    • Industry's lowest jitter with <50 fs RMS
    • Cascaded PLL architecture enables lower total solution BOM
  • WEBENCH® Clock Architect accelerates time-to-market
    • Enter requirements, select from suggested solutions, and simulate design
    • Build a complete, optimized clock tree in minutes
