MAX9451 - Microsemi

MAX9451 High-Precision Clock Generators

The MAX9450/MAX9451/MAX9452 clock generators provide high-precision clocks for timing in SONET/SDH systems or Gigabit Ethernet systems. The MAX9450/ MAX9451/MAX9452 can also provide clocks for the highspeed and high-resolution ADCs and DACs in 3G base stations. Additionally, the devices can also be used as a jitter attenuator for generating high-precision CL.
