FEMTOCLOCK™ CRYSTAL-TO-  
ICS843SDN  
3.3V LVPECL CLOCK GENERATOR  
General Description  
Features  
The ICS843SDN is a Gigabit Ethernet Clock  
One differential 3.3V LVPECL output  
Generator and a member of the HiPerClocksTM  
family of high performance devices from IDT. The  
ICS843SDN uses a 24MHz crystal to synthesize  
120MHz. The ICS843SDN uses IDT’s 3rd generation  
S
IC  
Crystal oscillator interface designed for 23.2MHz – 30MHz,  
HiPerClockS™  
18pF parallel resonant crystal  
Output frequency range: 116MHz – 150MHz  
VCO range: 580MHz – 750MHz  
low phase noise VCO technology, and can achieve <1ps rms  
phase jitter performance over the 12kHz – 20MHz integration  
range. The ICS843SDN is packaged in a small 8-pin TSSOP,  
making it ideal for use in systems with limited board space.  
Output duty cycle range: 47% – 53%  
RMS phase jitter @ 120MHz, using a 24MHz crystal  
(12kHz – 20MHz): 0.81ps (typical)  
Full 3.3V supply mode  
0°C to 70°C ambient operating temperature  
Industrial temperature information available upon request  
Available in lead-free (RoHS 6) package
