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:
