Resources for 844441I
Description
The 844441I is a low jitter, high performance clock generator and a member of the FemtoClock® family of silicon timing products. The 844441I is designed for use in applications using the SAS and SATA interconnect. The 844441I 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 844441I features down and center spread spectrum (SSC) clocking techniques.
