ICS843003AG REV. A FEBRUARY 19, 2008
General Description
The ICS843003 is a 3 differential output LVPECL
Synthesizer designed to generate Ethernet refer-
ence clock frequencies and is a member of the
HiPerClocksfamily of high performance clock
solutions from IDT. Using a 31.25MHz or
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.
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 3rd generation 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.
Features
Three 3.3V LVPECL outputs on two banks, A Bank with one
LVPECL pair and B Bank with 2 LVPECL output pairs
Using a 31.25MHz or 26.041666 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: 560MHz – 700MHz
RMS phase jitter @ 156.25MHz (1.875MHz - 20MHz):
0.51ps (typical)
