Description

The 843442I is a low jitter, high performance clock generator and a member of the FemtoClock™ family of silicon timing products. The 843442I is designed for use in applications using the SAS and SATA interconnect. The 843442I uses an external, 25MHz, parallel resonant crystal to generate two selectable output frequencies: 75MHz and 150MHz. This silicon based approach provides excellent frequency stability and reliability. The 843442I features down and center spread spectrum (SSC) clocking techniques.
