  Uncompromised Clocking Solution for 16-Bit 2.5Gsps
  High Performance DAC
  Design Note 555
  Clarence Mayott
  Introduction
  The LTC В®2000 16-bit 2.5Gsps DAC offers excellent
  AC performance. For many DAC applications, phase
  noise, noise spectral density (NSD), and spurious
  free dynamic range (SFDR) are critical to maximize
  the number of possible channels in a band without
  eroding the signal to noise ratio (SNR) in the band
  of interest. High speed DACs require a clean sample
  clock to achieve the best possible noise and spurious
  performance. Using the ultralow noise and spurious
  LTC6946 PLL synthesizer as a clock source for the
  LTC2000 maximizes system performance (FigureВ 1). 16-Bit High Speed DAC
  The high spectral purity and low noise of the LTC2000
  make it an excellent signal generator. FigureВ 2 highlights the excellent additive phase noise performance
  of the LTC2000 of –165dBc/Hz at 1MHz offset and
  –147dBc/Hz at 10kHz offset with a 65MHz output. For
  output frequencies up to 100MHz, the LTC2000 has
  NSD better than –166dBm/Hz and SFDR better than
  76dB. For higher output frequencies up to 1GHz, the …
