Features, Applications


Advanced programmable PLL design Very low Jitter and Phase Noise 40ps Pk-Pk typical) Output frequency to 375MHz CMOS. Supports differential CMOS output to produce PECL, LVDS inputs. Crystal inputs: o Fundamental crystal: 3 RD overtone crystal: 75MHz o Reference input: to 200MHz Accepts <1.0V reference signal input voltage One programmable I/O pin can be configured as Output Enable (OE), or Frequency Selection input (FSEL), or Reference clock. Single 10% power supply Operating temperature range from C Available in 8-pin MSOP/SOIC, 6-pin SOT Green/ RoHS compliant packages.


The is a low-cost general purpose frequency synthesizer and a member of PhaseLink's Factory Programmable `Quick Turn Clock (QTC)' family. PhaseLink's PL611-30 product family can generate any output frequency to 375 MHz from fundamental crystal input between 10 MHz - 30 MHz, a 3rd overtone crystal to 75Mhz. The PL611-30 produces differential CMOS outputs to support PECL, LVDS, and CMOS inputs.
