8V44S269 - 10-Output Clock Synthesizer

General Description

The 8V44S269 is a ten LVDS/LVTTL output clock synthesizer designed for instrumentation and wireless applications.

The device generates four copies of a 125MHz, two copies of a 100MHz differential LVDS clock and one 50MHz (LVCMOS) signal with excellent phase jitter performance.

Key Features

  • Third generation FemtoClock® technology.
  • 125MHz, 100MHz and 50MHz output clocks synthesized from a 25MHz reference clock or fundamental mode crystal.
  • Six differential LVDS clock outputs.
  • QA[0:3] outputs (125MHz) are LVDS compatible.
  • QB[0:1] outputs (100MHz) are LVDS compatible.
  • Four single-ended LVCMOS-compatible reference clock outputs.
  • QC output (50MHz) is LVCMOS 3.3V, 2.5V or 1.8V compatible.
  • QREF[0:2] (25MHz) are LVCMOS.

FemtoClock® Crystal-to-LVDS, LVCMOS 10-Output Clock Synthesizer 8V44S269 Datasheet General Description The 8V44S269 is a ten LVDS/LVTTL output clock synthesizer designed for instrumentation and wireless applications. The device generates four copies of a 125MHz, two copies of a 100MHz differential LVDS clock and one 50MHz (LVCMOS) signal with excellent phase jitter performance. The PLL is optimized for a reference frequency of 25MHz. Both a crystal interface and a single-ended input are supported for the reference frequency. Three LVCMOS outputs duplicate the reference frequency and are provided for clock tree cascade purpose. Each of the four LVCMOS outputs can be supplied with either 3.3V, 2.5V or 1.8V, forming the respective LVCMOS output levels of 3.3V, 2.5V or 1.8V.
