ESCRIPTION
The ICS843003I-01 is a 3 differential output
LVPECL Synthesizer designed to generate
Ethernet reference clock frequencies and is a
member of the HiPerClocks amily of high per-
formance 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 dif-
ferential LVPECL output pairs.
The two banks have their own dedicated frequency se-
lect pins and can be independently set for the frequen-
cies mentioned above. The ICS843003I-01 uses ICS’ 3rd
generation low phase noise VCO technology and can
achieve 1ps or lower typical rms phase jitter, easily meet-
ing Ethernet jitter requirements. The ICS843003I-01 is
packaged in a small 24-pin TSSOP package.
