PRELIMINARY

ICS843003I-01

Integrated

Circuit

Systems, Inc.

FEMTOCLOCKS™ C RYSTAL-TO-3.3V LVPECL

FREQUENCY SYNTHESIZER

GENERAL DESCRIPTION

FEATURES

The ICS843003I-01 is a 3 differential output

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

one LVPECL pair and B Bank with 2 LVPECL output pairs

ICS

LVPECL Synthesizer designed to generate

Ethernet reference clock frequencies and is a

member of the HiPerClocks™family of high per-

formance clock solutions from ICS. Using a

HiPerClockS™

• Using a 19.53125MHz or 25MHz crystal, the two output

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

156.25MHz or 125MHz

19.53125MHz or 25MHz, 18pF parallel resonant crystal, the

following frequencies can be generated based on the

settings of 4 frequency select pins (DIV_SEL[A1:A0],

DIV_SEL[B1:B0]): 625MHz, 312.5MHz, 156.25MHz, and

125MHz. The 843003I-01 has 2 output banks, Bank A with

1 differential LVPECL output pair and Bank B with 2 dif-

ferential LVPECL output pairs.

• Selectable crystal oscillator interface or LVCMOS/LVTTL

single-ended input

• VCO range: 490MHz to 680MHz

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

0.53ps (typical)

• 3.3V output supply mode

The two banks have their own dedicated frequency se-

lect pins and can be independently set for the frequen-

cies mentioned above. The ICS843003I-01 uses ICS’ 3rd

generation low phase noise VCO technology and can

achieve 1ps or lower typical rms phase jitter, easily meet-

ing Ethernet jitter requirements. The ICS843003I-01 is

packaged in a small 24-pin TSSOP package.

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