Overview
Low Voltage, Low Skew, 1.
244GHz PLL Clock Synthesizer 843S06 DATA SHEET GENERAL DESCRIPTION The 843S06 is a low voltage, low skew 3.
3V LVPECL Clock Synthesizer.
The device targets clock distribution in SDH/SONET telecommunication systems but is well suited for a wide range of applications requiring high performance high-speed clock synthesis.
The device implements a fully integrated multiplying PLL including: • An on-chip analog voltage controlled oscillator (VCO) • Phase-frequency detector • Programmable frequency dividers (prescalers) The loop filter is external in order to optimize the PLL for different applications.
As an option, the 843S06 may be operated with an external voltage controlled crystal oscillator for applications demanding a high-Q oscillator.
