FemtoClock™ Crystal-to-HSTL  
Frequency Synthesizer  
ICS8421004I-01  
DATA SHEET  
General Description  
Features  
The ICS8421004I-01 is a 4 output HSTL Synthesizer  
optimized to generate Ethernet reference clock  
frequencies. Using a 25MHz, 18pF parallel resonant  
crystal, the following frequencies can be generated  
based on the 2 frequency select pins (F_SEL[1:0]):  
Four HSTL outputs (VOH_MAX = 1.5V)  
S
IC  
Selectable crystal oscillator interface or LVCMOS/LVTTL  
HiPerClockS™  
single-ended input  
Supports the following output frequencies: 156.25MHz, 125MHz,  
62.5MHz  
156.25MHz, 125MHz and 62.5MHz. The ICS8421004I-01 uses  
IDT’s 3rd generation low phase noise VCO technology and can  
achieve 1ps or lower typical rms phase jitter, easily meeting Ethernet  
jitter requirements. The ICS8421004I-01 is packaged in a small  
24-pin TSSOP package.  
VCO range: 560MHz - 680MHz  
RMS phase jitter @ 156.25MHz, using a 25MHz crystal  
(1.875MHz - 20MHz): 0.44ps (typical)  
Power supply modes:  
Core/Output  
3.3V/1.8V  
2.5V/1.8V  
-40°C to 85°C ambient operating temperature  
Available in both standard (RoHS 5) and lead-free (RoHS 6)  
packages
