Programmable FemtoClock® NG LVPECL/LVDS  
Clock Generator with 4-Outputs  
IDT8T49N004I  
DATASHEET  
General Description  
Features  
The IDT8T49N004I is a four output Clock Generator with selectable  
LVDS or LVPECL outputs. The IDT8T49N004I can generate any one  
of four frequencies from a single crystal or reference clock. The four  
frequencies are selected from the Frequency Selection Table (Table  
3A) and are programmed via I2C interface. The four predefined  
frequencies are selected in the user application by two frequency  
selection pins. Note the desired programmed frequencies must be  
used with the corresponding crystal or clock frequency as indicated  
in Table 3A.  
Fourth Generation FemtoClock NG PLL technology  
Four selectable LVPECL or LVDS outputs via I2C  
CLK, nCLK input pair can accept the following differential input  
levels: LVPECL, LVDS, HCSL  
FemtoClock NG VCO Range: 1.91GHz - 2.5GHz  
RMS phase jitter at 156.25MHz (12kHz - 20MHz):  
228fs (typical)  
RMS phase jitter at 156.25MHz (10kHz - 1MHz): 175fs (typical)  
Full 2.5V or 3.3V power supply  
I2C programming interface  
Excellent phase noise performance is maintained with IDT’s Fourth  
Generation FemtoClock® NG PLL technology, which delivers  
sub-400fs RMS phase jitter.  
PCI Express (2.5Gb/s), Gen 2 (5Gb/s), and Gen 3 (8Gb/s)  
jitter compliant  
-40°C to 85°C ambient operating temperature
