ICS8422002I
FEMTOCLOCKS CRYSTAL-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 IDT. Using
a 26.5625MHz 18pF parallel resonant cr ystal, 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 IDT’ 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 (RoHS5) and lead-free (RoHS 6)
