ICS843101I-312
FEMTOCLOCKSCRYSTAL-TO-LVPECL
312.5MHZ FREQUENCY MARGINING SYNTHESIZER
PRELIMINARY
GENERAL DESCRIPTION
The ICS843101I-312 is a low phase-noise
frequency margining synthesizer with fre-
quency margining capability and is a member of
the HiPerClockS family of high performance
clock solutions from ICS. In the default mode,
the device nominally generates a 312.5MHz LVPECL output
clock signal from a 25MHz crystal input. There is also a
frequency margining mode available where the device can
be programmed, using the serial interface, to vary the
output frequency up or down from nominal in 2% steps.
The ICS843101I-312 is provided in a 16-pin TSSOP.
FEATURES
One 312.5MHz nominal LVPECL output
Selectable crystal oscillator interface designed for 25MHz,
18pF parallel resonant crystal or LVCMOS/LVTTL
single-ended input
Output frequency can be varied in 2% steps ± from
nominal
VCO range: 560MHz - 690MHz
RMS phase jitter @ 312.5MHz, using a 25MHz crystal
(1.875MHz - 20MHz): 0.52ps (typical)
