Clock Generator 32-Pin TQFP EP

The MAX9450/MAX9451/MAX9452 clock generators provide high-precision clocks for timing in SONET/SDH systems or Gigabit Ethernet systems. ? Integrated VCXO Provides a Cost-Effective
Solution for High-Precision Clocks
? 8kHz to 500MHz Input Frequency Range
? 15MHz to 160MHz Output Frequency Range
? I2C or SPI Programming for the Input and Output
Frequency Selection
? PLL Lock Range > ±60ppm
? Two Differential Outputs with Three Types of
Signaling: LVPECL, LVDS, or HSTL
? Input Clock Monitor with Hitless Switch
? Internal Holdover Function within ±20ppm of the
Nominal Frequency
? Low Output CLK Jitter: < 0.8ps RMS in the 12kHz
to 20MHz Band
? Low Phase Noise > -130dBc at 100kHz, > -140dBc
at 1MHz
