FEMTOCLOCKS CRYSTAL-TO-HSTL
FREQUENCY SYNTHESIZER
ICS8421002I
IDT / ICS HSTL FREQUENCY SYNTHESIZER

ICS8421002I REV B
MARCH 02, 2009
GENERAL DESCRIPTION
The ICS8421002I is a 2 output HSTL 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 18pF parallel resonant crystal,
the following frequencies can be generated based on the 2
frequency select pins (F_SEL[1:0]): 212.5MHz, 187.5MHz,
159.375MHz, 106.25MHz and 53.125MHz. The ICS8421002I 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 ICS8421002I is packaged in a
small 20-pin TSSOP package.
FEATURES
Two HSTL outputs (VOHmax = 1.5V)
Selectable crystal oscillator interface
or LVCMOS/LVTTL single-ended input
Supports the following output frequencies: 212.5MHz,
187.5MHz, 159.375MHz, 106.25MHz, 53.125MHz
VCO range: 560MHz - 680MHz
RMS phase jitter @ 212.5MHz, using a 26.5625MHz crystal
(637kHz - 10MHz): 0.59ps (typical)
Power supply modes:
Core/Output
3.3V/1.8V
2.5V/1.8V
-40°C to 85°C ambient operating temperature
Available in both standard (RoHS 5) an lead-free (RoHS 6)
