PRELIMINARY

FEMTOCLOCKS™ CRYSTAL-TO-LVDS

FREQUENCY SYNTHESIZER

ICS844003I-02

GENERAL DESCRIPTION

FEATURES

• Three 3.3V LVDS outputs on two banks, Bank A with one

LVDS pair and Bank B with two LVDS output pairs

The ICS844003I-02 is a 3 differential output LVDS

ICS

HiPerClockS™

Synthesizer designed to generate Ethernet and PCI

Express™ reference clock frequencies and is a

• Using a 31.25MHz, 26.041666, or 25MHz crystal, the two

output banks can be independently set for 625MHz, 500MHz

312.5MHz, 250MHz, 156.25MHz, 125MHz or 100MHz

member of the HiPerClocks™ family of high

performance clock solutions from IDT. Using a

31.25MHz, 26.041666MHz, or 25MHz, 18pF parallel resonant

crystal, the following frequencies can be generated based on the

settings of 4 frequency select pins (DIV_SELA[1:0],

DIV_SELB[1:0]): 625MHz, 500MHz, 312.5MHz, 250MHz,

156.25MHz, 125MHz, and 100MHz.The 844003I-02 has 2 output

banks, Bank A with one differential LVDS output pair and Bank B

with two differential LVDS output pairs.

• Selectable crystal oscillator interface or LVCMOS/LVTTL

single-ended input

• VCO range: 490MHz to 680MHz

• RMS phase jitter @ 125MHz (1.875MHz - 20MHz):

0.50ps (typical)

• Full 3.3V supply mode

The two banks have their own dedicated frequency select pins

and can be independently set for the frequencies mentioned

above.The ICS844003I-02 uses IDT’s 3rd generation low phase

noise VCO technology and can achieve 1ps or lower typical

rms phase jitter, easily meeting Ethernet jitter requirements.

The ICS844003I-02 is packaged in a 32-pin VFQFN package.

• -40°C to 85°C ambient operating temperature

• Available in both standard (RoHS 5) and lead-free (RoHS 6)

packages
