FEMTOCLOCKS™ CRYSTAL-TO-HSTL

FREQUENCY SYNTHESIZER

ICS8421002I

GENERAL DESCRIPTION

FEATURES

The ICS8421002I is a 2 output HSTL Synthesizer

• Two HSTL outputs (VOHmax = 1.5V)

ICS

HiPerClockS™

optimized to generate Fibre Channel reference clock

frequencies and is a member of the HiPerClocks^TM

family of high performance clock solutions from IDT.

Using a 26.5625MHz 18pF parallel resonant crystal,

• 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

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 3^rdgeneration 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.

• 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)
