PRELIMINARY

FEMTOCLOCKS™ CRYSTAL-TO-LVDS

FREQUENCY SYNTHESIZER

ICS844003

GENERAL DESCRIPTION

FEATURES

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

pair and B Bank with 2 LVDS output pairs

The ICS844003 is a 3 differential output LVDS

ICS

Synthesizer designed to generate Ethernet reference

HiPerClockS™

clock frequencies and is a member of the

HiPerClocks™ family of high performance clock

solutions from IDT. Using a 31.25MHz or

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

banks can be independently set for 625MHz, 312.5MHz,

156.25MHz or 125MHz

26.041666MHz, 18pF parallel resonant crystal, the following

frequencies can be generated based on the settings of four

frequency select pins (DIV_SEL[A1:A0], DIV_SEL[B1:B0]):

625MHz, 312.5MHz, 156.25MHz, and 125MHz. The ICS844003

has two 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: 560MHz to 700MHz

• RMS phase jitter @ 156.25MHz (1.875MHz - 20MHz):

0.63ps (typical)

• 3.3V output supply mode

The two banks have their own dedicated frequency select

pins and can be independently set for the frequencies

mentioned above. The ICS844003 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 ICS844003 is packaged in a small 24-

pin TSSOP package.

• 0°C to 70°C ambient operating temperature

• Available in both standard (RoHS5) and lead-free (RoHS 6)

packages
