19-0547; Rev 3; 11/07 EVALUATION KIT AVAILABLE High-Precision Clock Generators with Integrated VCXO MAX9450/MAX9451/MAX9452 General Description Features The MAX9450/MAX9451/MAX9452 clock generators Integrated VCXO Provides a Cost-Effective provide high-precision clocks for timing in SONET/SDH Solution for High-Precision Clocks systems or Gigabit Ethernet systems. The MAX9450/ 8kHz to 500MHz Input Frequency Range MAX9451/MAX9452 can also provide clocks for the high- 15MHz to 160MHz Output Frequency Range speed and high-resolution ADCs and DACs in 3G base I2C or SPI Programming for the Input and Output stations. Additionally, the devices can also be used as a Frequency Selection jitter attenuator for generating high-precision CLK signals. PLL Lock Range > ±60ppm The MAX9450/MAX9451/MAX9452 feature an integrated Two Differential Outputs with Three Types of VCXO. This configuration eliminates the use of an exter- Signaling: LVPECL, LVDS, or HSTL nal VCXO and provides a cost-effective solution for gen- Input Clock Monitor with Hitless Switch erating high-precision clocks. The MAX9450/MAX9451/MAX9452 feature two differential inputs and clock out- Internal Holdover Function within ±20ppm of the puts. The inputs accept LVPECL, LVDS, differential sig- Nominal Frequency nals, and LVCMOS. The input reference clocks range Low Output CLK Jitter: < 0.8ps RMS in the 12kHz from 8kHz to 500MHz. to 20MHz Band The MAX9450/MAX9451/MAX9452 offer LVPECL, HSTL, Low Phase Noise > -130dBc at 100kHz, > -140dBc at 1MHz and LVDS outputs, respectively. The output range is upto 160MHz, depending on the selection of crystal. The Ordering Information input and output frequency selection is implementedthrough the I2C or SPITM interface. The MAX9450/ PART PIN-PACKAGE OUTPUT PKG CODE MAX9451/MAX9452 feature clock output jitter less than MAX9450EHJ 32 TQFP-EP* LVPECL H32E-6 0.8ps RMS (in a 12kHz to 20MHz band) and phase-noise attenuation greater than -130dBc/Hz at 100kHz.
