MAX9451 - High-Precision Clock Generators

Download the MAX9451 datasheet PDF. This datasheet also covers the MAX9450 variant, as both devices belong to the same high-precision clock generators family and are provided as variant models within a single manufacturer datasheet.

General Description

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.

Key Features

  • 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 F.

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 CLK signals. The MAX9450/MAX9451/MAX9452 feature an integrated VCXO. This configuration eliminates the use of an external VCXO and provides a cost-effective solution for generating high-precision clocks. The MAX9450/MAX9451/ MAX9452 feature two differential inputs and clock outputs.
