PRELIMINARY  
FEMTOCLOCKS™ CRYSTAL-TO-LVDS  
FREQUENCY SYNTHESIZER  
ICS844003I-04  
GENERAL DESCRIPTION  
FEATURES  
The ICS844003I-04 is a 3 differential output LVDS  
• Three LVDS outputs on two banks, Bank A with one LVDS  
pair and Bank B with 2 LVDS output pairs  
ICS  
HiPerClockS™  
Synthesizer designed to generate Ethernet  
reference clock frequencies and is a member of  
the HiPerClocksfamily of high performance clock  
solutions from IDT. Using a 19.53125MHz, 20MHz  
• Using a 19.53125MHz, 20MHz or 25MHz crystal, the two  
output banks can be independently set for 625MHz,  
500MHz, 312.5MHz, 250MHz, 156.25MHz, 125MHz or  
100MHz  
or 25MHz, 18pF parallel resonant crystal, the following  
frequencies can be generated based on the settings of 4  
frequency select pins (DIV_SELA[1:0], DIV_SELB[1:0]):  
625MHz, 500MHz, 312.5MHz, 250MHz, 156.25MHz, 125MHz  
and 100MHz. The ICS844003I-04 has 2 output banks, Bank A  
with one differential LVDS output pair and Bank B with two  
differential LVDS output pairs.  
• Selectable crystal oscillator interface or LVCMOS/LVTTL  
single-ended input  
• VCO range: 490MHz to 680MHz  
• RMS phase jitter @ 125MHz (1.875MHz - 20MHz):  
0.50ps (typical)  
• 3.3V output supply mode  
The two banks have their own dedicated frequency select pins  
and can be independently set for the frequencies mentioned  
above.The ICS844003I-04 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 ICS844003I-04 is packaged in a 32-pin VFQFN package.  
• -40°C to 85°C ambient operating temperature  
• Available in both standard (RoHS 5) and lead-free (RoHS 6)  
packages
