ICS844003BI-01
FEMTOCLOCKS CRYSTAL-TO-LVDS
FREQUENCY SYNTHESIZER
PRELIMINARY
GENERAL DESCRIPTION
The ICS844003BI-01 is a 3 differential output
LVDS 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_SELA[1:0],
DIV_SELB[1:0]): 625MHz, 312.5MHz, 156.25MHz, and
125MHz. The 844003BI-01 has 2 output banks, Bank A with
1 differential LVDS output pair and Bank B with 2 differen-
tial LVDS output pairs.
The two banks have their own dedicated frequency select
pins and can be independently set for the frequencies men-
tioned above. The ICS844003BI-01 uses ICS’ 3rd genera-
tion low phase noise VCO technology and can achieve 1ps
or lower typical rms phase jitter, easily meeting Ethernet
jitter requirements. The ICS844003BI-01 is packaged in a
small 24-pin TSSOP package.
FEATURES
Three LVDS outputs on two banks, Bank A with one
LVDS pair and Bank B with 2 LVDS 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):
0.56ps (typical)
3.3V output supply mode
-40°C to 85°C ambient operating temperature
Available in both standard and lead-free RoHS-compliant
packages
