ICS8422002I
FEMTOCLOCKSCRYSTAL-TO-
LVHSTL FREQUENCY SYNTHESIZER
PRELIMINARY
GENERAL DESCRIPTION
The ICS8422002I is a 2 output LVHSTL
Synthesizer optimized to generate Fibre
Channel reference clock frequencies and is a
member of the HiPerClocksTM family of high
performance clock solutions from ICS. 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
ICS8422002I uses ICS’ 3rd generation low phase noise
VCO technology and can achieve 1ps or lower typical rms
phase jitter, easily meeting Fibre Channel jitter
requirements. The ICS8422002I is packaged in a 20-pin
TSSOP package.
FEATURES
Two LVHSTL outputs (VOHmax = 1.2V)
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 and lead-free RoHS-compliant
packages
