FemtoClock LVCMOS/Crystal-to-3.3V,
2.5V LVPECL Frequency Synthesizer
ICS843004I
General Description
The ICS843004I is a 4 output LVPECL synthesizer
optimized to generate Fibre Channel reference clock
frequencies. Using a 26.5625MHz 18pF parallel
resonant crystal, the following frequencies can be
generated based on the two frequency select pins
(F_SEL[1:0]): 212.5MHz, 187.5MHz, 159.375MHz, 156.25MHz,
106.25MHz, and 53.125MHz. The ICS843004I uses IDT’s 3rd
generation low phase noise VCO technology and can achieve 1ps or
lower typical rms phase jitter, easily meeting Fibre Channel jitter
requirements. The ICS843004I is packaged in a small 24-pin TSSOP
package.
Features
Four 3.3V differential LVPECL output pairs
Selectable crystal oscillator interface or LVCMOS/LVTTL
single-ended clock input
Supports the following output frequencies: 212.5MHz, 187.5MHz,
159.375MHz, 156.25MHz, 106.25MHz, 53.125MHz
VCO range: 560MHz – 680MHz
Output skew: 50ps (maximum)
RMS phase jitter @ 212.5MHz, using a 26.5625MHz crystal
(2.55MHz – 20MHz): 0.47ps (typical)
Full 3.3V or 2.5V supply modes
-40°C to 85°C ambient operating temperature
Available in both standard (RoHS 5) and lead-free (RoHS 6)
