FEMTOCLOCKS CRYSTAL-TO-LVPECL 350MHZ FREQUENCY SYNTHESIZER

ICS843207B-350

The ICS843207B-350 is a low phase-noise
frequency synthesizer that targets clocking for

HiPerClockS high performance interfaces such as SPI4.2 and
is a member of the HiPerClockS family of high
perfor mance 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. The ICS843207B-
350 is provided in a 48-pin LQFP package.
• 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
• 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 packages
