FEMTOCLOCKS™ CRYSTAL-TO-3.3V LVPECL

FREQUENCY SYNTHESIZER

ICS843003

General Description

Features

The ICS843003 is a 3 differential output LVPECL

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

LVPECL pair and B Bank with 2 LVPECL output pairs

Synthesizer designed to generate Ethernet refer-

ence clock frequencies and is a member of the

HiPerClocks™family of high performance clock

solutions from IDT. Using a 31.25MHz or

HiPerClockS™

• Using a 31.25MHz or 26.041666 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 4 fre-

quency select pins (DIV_SEL[A1:A0], DIV_SEL[B1:B0]): 625MHz,

312.5MHz, 156.25MHz, and 125MHz. The 843003 has 2 output

banks, Bank A with 1 differential LVPECL output pair and Bank B

with 2 differential LVPECL output pairs.

• Selectable crystal oscillator interface

or LVCMOS/LVTTL single-ended input

• VCO range: 560MHz – 700MHz

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

0.51ps (typical)

Offset

Noise Power

The two banks have their own dedicated frequency select pins and

can be independently set for the frequencies mentioned above.

The ICS843003 uses IDT’s 3^rdgeneration low phase noise VCO

technology and can achieve 1ps or lower typical rms phase jitter,

easily meeting Ethernet jitter requirements. The ICS843003 is

packaged in a small 24-pin TSSOP package.

100Hz................ -96.8 dBc/Hz

1kHz .................. -119.1 dBc/Hz

10kHz ................ -126.4 dBc/Hz

100kHz .............. -127.0 dBc/Hz

• Full 3.3V supply mode

• 0°C to 70°C ambient operating temperature

• Industrial temperature available upon request
