- Part Number:
- 843441AM-100LF
- Manufacturer:
- IDT, Integrated Device Technology Inc
- Ventron No:
- 2983486-843441AM-100LF
- Description:
- IC CLK GEN SAS/SATA 8SOIC
- Datasheet:
- 843441AM-100LF
Description
The 843441 is a low jitter, high performance clock generator designed for use in SAS, SAS-2, and SATA systems. It 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.
Features
Designed for use in SAS, SAS-2, and SATA systems
Center (40.33%) Spread Spectrum Clocking (SSC)
Down (-0.30% or -0.60%) SSC
Better frequency stability than SAW oscillators
One differential 3.3V LVPECL output
Crystal oscillator interface designed for 25MHz (CL 18pF) frequency
External fundamental crystal frequency ensures high reliability and low aging
Selectable output frequencies: 75MHz, 100MHz, 150MHz, 300MHz
Output frequency is tunable with external capacitors
RMS phase jitter: 1.33ps (typical)
3.3V operating supply
0°C to 70°C ambient operating temperature
Industrial temperature available upon request
Available in lead-free (RoHS 6) package
843441-150 Functional replacement part use BT49N242i
Applications
SAS, SAS-2, and SATA systems
