ICS840-77  
77.76MHZ, LVCMOS/LVTTL  
OSCILLATOR REPLACEMENT  
Integrated  
Circuit  
Systems, Inc.  
GENERAL DESCRIPTION  
FEATURES  
The ICS840-77 is a SONET Oscillator Replace- One LVCMOS/LVTTL output, 15Ω output impedence  
ICS  
ment and a member of the HiPerClocksTM  
Crystal oscillator interface designed for 19.44MHz,  
family of high performance devices from ICS.  
18pF parallel resonant crystal  
HiPerClockS™  
The ICS840-77 uses a 19.44MHz crystal to  
synthesize 77.76MHz. The ICS840-77 has  
Output frequency: 77.76MHz  
Random jitter: 2.82ps (typical)  
Deterministic jitter: 0.205ps (typical)  
3.3V operating supply  
excellent jitter performance. The ICS840-77 is packaged in  
a small 8-pin TSSOP, making it ideal for use in systems with  
limited board space.  
0°C to 70°C ambient operating temperature  
Available in both standard and lead-free RoHS-compliant  
packages
