GENERAL DESCRIPTION
The AD9511 provides a multi-output clock distribution function along with an on-chip PLL core. The design emphasizes low jitter and phase noise to maximize data converter performance. Other applications with demanding phase noise and jitter requirements also benefit from this part.

FEATURES
   Low phase noise phase-locked loop core
      Reference input frequencies to 250 MHz
      Programmable dual-modulus prescaler
      Programmable charge pump (CP) current
      Separate CP supply (VCPS) extends tuning range
   Two 1.6 GHz, differential clock inputs
   5 programmable dividers, 1 to 32, all integers
   Phase select for output-to-output coarse delay adjust
   3 independent 1.2 GHz LVPECL outputs
      Additive output jitter 225 fs rms
   2 independent 800 MHz/250 MHz LVDS/CMOS clock outputs
      Additive output jitter 275 fs rms
      Fine delay adjust on 1 LVDS/CMOS output
   Serial control port
   Space-saving 48-lead LFCSP
