FEMTOCLOCK CRYSTAL-TO-3.3V
LVPECL FREQUENCY SYNTHESIZER
ICS843003I-01
IDT / ICS 3.3V LVPECL FREQUENCY SYNTHESIZER
1
ICS843003AGI-01 REV A March 2, 2009
GENERAL DESCRIPTION
The ICS843003I-01 is a 3 differential output
LVPECL Synthesizer designed to generate Ethernet
reference clock frequencies and is a member of
the HiPerClocks family of high performance clock
solutions from ICS. Using a 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 differential LVPECL output pairs.
The two banks have their own dedicated frequency select
pins and can be independently set for the frequencies
mentioned abo ve. The ICS843003I-01 uses ICS’ 3rd
generation low phase noise VCO technology and can
achieve 1ps or lower typical rms phase jitter, easily meeting
Ether net jitter requirements . The ICS843003I-01 is
packaged in a small 24-pin TSSOP package.
FEATURES
Three 3.3V LVPECL outputs on two banks, A Bank with one
LVPECL pair and B Bank with two LVPECL output pairs
Using a 19.53125MHz or 25MHz crystal, the two output
banks can be independently set for 625MHz, 312.5MHz,
156.25MHz or 125MHz
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
-40°C to 85°C ambient operating temperature
Available in both standard and lead-free RoHS compliant
packages
