FemtoClock® Crystal/LVCMOS-to-  
3.3V LVPECL Frequency Synthesizer  
843004I-04  
DATASHEET  
GENERAL DESCRIPTION  
FEATURES  
• Four LVPECL outputs  
The 843004I-04 is a 4 output LVPECL Synthesizer optimized  
to generate clock frequencies for a variety of high performance  
applications. This device can select its input reference clock  
from either a crystal input or a single-ended clock signal. It can  
be configured to generate 4 outputs with individually selectable  
divide-by-one or divide-by-four function via the 4 frequency  
select pins (F_SEL[3:0]). The 843004I-04 uses IDT’s 3rd  
generation low phase noise VCO technology and can achieve  
1ps or lower typical rms phase jitter. This ensures that it will  
• Selectable crystal oscillator interface  
or LVCMOS/LVTTL single-ended input  
• Supports the following applications: SONET/SDH, SATA,  
or 10Gb Ethernet  
• Output frequency range: 140MHz - 170MHz,  
560MHz - 680MHz  
easily meet clocking requirements for SDH (STM-1/STM-4/STM- • VCO range: 560MHz - 680MHz  
16) and SONET (OC-3/OC12/OC-48).This device is suitable for  
• Crystal oscillator and CLK range: 17.5MHz - 21.25MHz  
multi-rate and multiple port line card applications.The 843004I-  
04 is conveniently packaged in a small 24-pinTSSOP package.  
• RMS phase jitter @ 622.08MHz output, using a 19.44MHz  
crystal (12kHz - 20MHz): 0.82ps (typical)  
• RMS phase jitter @ 156.25MHz output, using a 19.53125MHz  
crystal (1.875MHz - 20MHz): 0.57ps (typical)  
• RMS phase jitter @ 155.52MHz output, using a 19.44MHz  
crystal (12kHz - 20MHz): 0.94ps (typical)  
• Full 3.3V supply mode  
• -40°C to 85°C ambient operating temperature  
• Available in lead-free RoHS compliant package
