MX1DS10P 15 GHz Ultra Variable Broadband Prescaler Application Features The MX1DS10P is ideal for phase locked Wide Operating Range: 0.05 - 15 loops and other synthesizers requiring large GHz and variable divide ratios. Other applications Variable Divide Ratios: 2 to 220 include trigger generation for high-speed Single-Ended and/or Differential measurement systems. The MX1DS10P can Drive be employed in high frequency phase locked High Input Sensitivity loops that can take advantage of the low 1/f Size: 6mm x 6mm noise of SiGe HBTs. General purpose test Single -3.3 V Power Supply instrumentation systems will also benefit from Low SSB Phase Noise: the high input sensitivity and broad frequency 153 dBc 10 kHz range.
