ICS840-75  
75MHZ, LVCMOS/LVTTL  
OSCILLATOR REPLACEMENT  
Integrated  
Circuit  
Systems, Inc.  
GENERAL DESCRIPTION  
FEATURES  
The ICS840-75 is a SAS/SATA Oscillator • One LVCMOS/LVTTL output, 15Ω output impedence  
ICS  
Replacement and  
a
member of the  
• Crystal oscillator interface designed for 25MHz,  
18pF parallel resonant crystal  
HiPerClocksTM family of high performance  
devices from ICS. The ICS840-75 uses a  
25MHz crystal to synthesize 75MHz. The  
HiPerClockS™  
• Output frequency: 75MHz  
ICS840-75 has excellent jitter performance. The ICS840-75  
is packaged in a small 8-pin TSSOP, making it ideal for  
use in systems with limited board space.  
• Random jitter: 3ps (typical)  
• Deterministic jitter: 0.14ps (typical)  
• 3.3V operating supply  
• 0°C to 70°C ambient operating temperature  
• Available in both standard and lead-free RoHS-compliant  
packages
