PRELIMINARY

FEMTOCLOCKS™ CRYSTAL-TO-

ICS8422002I-01

LVHSTL FREQUENCY SYNTHESIZER

General Description

Features

The ICS8422002I-01 is a 2 output LVHSTL

Synthesizer optimized to generate Ethernet

• Two LVHSTL outputs (V_OHmax = 1.2V)

• Selectable crystal oscillator interface or

HiPerClockS™

reference clock frequencies and is a member of the

LVCMOS/LVTTL single-ended input

HiPerClocks family of high performance clock

• Supports the following output frequencies: 156.25MHz,

solutions from IDT. Using a 25MHz 18pF parallel

125MHz, 62.5MHz

resonant crystal, the following frequencies can be generated

based on the 2 frequency select pins (F_SEL[1:0]): 156.25MHz,

125MHz and 62.5MHz. The ICS8422002I-01 uses IDT’s 3^rd

generation low phase noise VCO technology and can achieve 1ps

or lower typical rms phase jitter, easily meeting Ethernet jitter

requirements. The ICS8422002I-01 is packaged in a small 20-pin

TSSOP package.

• VCO range: 560MHz - 680MHz

• RMS phase jitter @ 156.25MHz, using a 25MHz crystal

(1.875MHz - 20MHz): 0.44ps (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)
