CS2600 - Fractional-N Clock Synthesizer and Clock Multiplier

General Description

The CS2600 is a system-clocking device incorporating a programmable phase-locked loop (PLL).

The hybrid analog/ digital PLL architecture comprises a delta-sigma fractional-N analog PLL and a digital frequency-locked loop (FLL).

Key Features

  • Clock frequency synthesizer incorporating delta-sigma fractional-N analog PLL.
  • Generates low-jitter 6.
  • 75 MHz clock (CLK_OUT) from 8.
  • 75 MHz timing reference (REF_CLK_IN).
  • Fractional clock multiplier and jitter reduction using hybrid analog/digital PLL.
  • Generates low-jitter 6.
  • 75 MHz clock (CLK_OUT), synchronized to a 50 Hz.
  • 30 MHz low-quality or intermittent frequency reference (CLK_IN).
  • Flexible timing reference source.
