FEMTOCLOCK™ CRYSTAL-TO-3.3V
LVPECL FREQUENCY SYNTHESIZER
ICS843003I-01
G
ENERAL
D
ESCRIPTION
The ICS843003I-01 is a 3 differential output
LVPECL Synthesizer designed to generate Ethernet
HiPerClockS™
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.
F
EATURES
• 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

The two banks have their own dedicated frequency select
pins and can be independently set for the frequencies

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.

Description
Division select pin for Bank B. Default = HIGH.
Pullup
LVCMOS/LVTTL interface levels.
VCO select pin. When Low, the PLL is bypassed and the crystal reference or
REF_CLK (depending on XTAL_SEL setting) are passed directly to the
Pullup
output dividers. Has an internal pullup resistor so the PLL is not bypassed by
default. LVCMOS/LVTTL interface levels.
Active HIGH Master Reset. When logic HIGH, the internal dividers are reset
causing the true outputs Qx to go low and the inver ted outputs nQx
Pulldown to go high. When logic LOW, the internal dividers and the outputs are
enabled. Has an internal pulldown resistor so the power-up default state of
outputs and dividers are enabled. LVCMOS/LVTTL interface levels.
Output supply pin for Bank A outputs.
Differential output pair. LVPECL interface levels.
Output enable Bank B. Active High output enable. When logic HIGH, the 2
output pairs on Bank B are enabled. When logic LOW, the output pairs drive
differential Low (QB0=Low, nQB0=High). Has an internal pullup resistor so
the default power-up state of outputs are enabled.
LVCMOS/LVTTL interface levels.
Output enable Bank A. Active High output enable. When logic HIGH, the
output pair on Bank A is enabled. When logic LOW, the output pair drives
differential Low (QA0=Low, nQA0=High). Has an internal pullup resistor so
the default power-up state of outputs are enabled. LVCMOS/LVTTL interface
levels.
Feedback divide select. When Low (default), the feedback divider is set for
÷25. When HIGH, the feedback divider is set for ÷32.
LVCMOS/LVTTL interface levels.
Analog supply pin.

Parallel resonant crystal interface. XTAL_OUT is the output, XTAL_IN is the
input. XTAL_IN is also the overdrive pin if you want to overdrive the crystal
circuit with a single-ended reference clock.
Single-ended reference clock input. Has an internal pulldown resistor to pull
Pulldown to low state by default. Can leave floating if using the crystal interface.
LVCMOS/LVTTL interface levels.
Crystal select pin. Selects between the single-ended REF_CLK or crystal
Pullup
interface. Has an internal pullup resistor so the crystal interface is selected
