Overview

Description

The 841202-245 is a two output clock synthesizer optimized to generate low jitter with or without spread spectrum modulation. Spread type and amount can be configured via the SSC control pins. Using a 25MHz, 18pF parallel resonant crystal, the device will generate HCSL clocks at either 25MHz, 100MHz, 125MHz or 250MHz. The 841202-245 uses a low jitter VCO and is packaged in a 32-pin VFQFN package.

Features

  • Two differential HCSL output pairs at: 100MHz, 125MHz or 250MHz
  • HCSL outputs can be terminated to drive LVDS loads up to 175MHz
  • 25MHz crystal interface
  • Supports the following output frequencies: 25MHz, 100MHz, 125MHz or 250MHz
  • VCO range: 250MHz - 700MHz
  • Supports SSC downspread at 0.05% and -0.75%, centerspread at ±0.25% and no spread options
  • Cycle-to-cycle jitter: 15ps (typical)
  • Period jitter, RMS: 2.5ps (typical)
  • Full 3.3V operating supply mode
  • 0°C to 70°C ambient operating temperature
  • Available in lead-free (RoHS 6) packages
