描述

The 843441 is a low jitter, high performance clock generator. The 843441 is designed for use in applications using the SAS and SATA interconnect. The 843441 uses an external, 25MHz, parallel resonant crystal to generate four selectable output frequencies: 75MHz, 100MHz, 150MHz, and 300MHz. This silicon based approach provides excellent frequency stability and reliability. The 843441 features down and center spread spectrum (SSC) clocking techniques.
