GENERAL DESCRIPTION
The ICS843207-350 is a lo w phase-noise
frequency margining synthesizer that targets
clocking for high perfor mance interfaces such
as SPI4.2 and is a member of the HiPerClockS
family of high performance clock solutions from
IDT. In the default mode, each output can be configured
individually to generate an 87.5MHz, 175MHZ or 350MHz
LVPECL output clock signal from a 14MHz cr ystal input.
There is also a frequency margining mode available where
the device can be configured, using control pins, to var y
the output frequency up or down from nominal by 5%. The
ICS843207-350 is provided in a 48-pin LQFP package.
FEATURES
Seven independently configurable LVPECL outputs at
87.5MHz, 175MHz or 350MHz
Individual high impedance control of each output
Selectable crystal oscillator interface designed for 14MHz,
18pF parallel resonant crystal or LVCMOS single-ended input
Output frequency can be varied ± 5% from nominal
VCO range: 620MHz - 750MHz
Full 3.3V supply mode
0°C to 70°C ambient operating temperature
Available in both standard (RoHS 5) and lead-free (RoHS 6)
