FemtoClock Crystal-to-LVCMOS/LVTTL
Frequency Synthesizer
ICS840004I
General Description
The ICS840004I is a 4 output LVCMOS/LVTTL
Synthesizer optimized to generate Fibre Channel
reference clock frequencies and is a member of the
HiPerClocksTM family of high performance clock
solutions from IDT. Using a 26.5625MHz or a
26.04166MHz, 18pF parallel resonant crystal, the following
frequencies can be generated based on the 2 frequency select pins
(F_SEL1:0): 212.5MHz, 159.375MHz, 156.25MHz, 106.25MHz, and
53.125MHz. The ICS840004I uses IDT’s 3rd generation low phase
noise VCO technology and can achieve 1ps or lower typical random
rms phase jitter, easily meeting Fibre Channel jitter requirements.
The ICS840004I is packaged in a small 20-pin TSSOP package.
Features
Four single-ended LVCMOS/LVTTL outputs
17
typical output impedance
Selectable crystal oscillator interface or single-ended input
Supports the following output frequencies: 212.5MHz,
159.375MHz, 156.25MHz, 106.25MHz and 53.125MHz
VCO range: 560MHz - 700MHz
RMS phase jitter at 212.5MHz (637kHz – 10MHz):
0.49ps (typical)
