FemtoClock Crystal-to-LVHSTL
Frequency Synthesizer
ICS8422002I
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.
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’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 ICS8422002I is packaged in a
20-pin TSSOP package.
Features
Two LVHSTL outputs (V
OH_max = 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 (RoHS 5) and lead-free (RoHS 6)
