General Description
ICS8402015I is a low phase noise Clock Synthesizer
ICS
and is a member of the HiPerClockS™family of high
HiPerClockS™ _{performance clock solutions from IDT. The device}
provides three banks of outputs and a reference clock.
Each bank can be enabled by using output enable
pins. A 25MHz or 50MHz, 18pF parallel resonant crystal is used to
generate 25MHz LVCMOS, 125MHz LVCMOS and 125MHz LVDS
outputs. ICS8402015I is packaged in a small, 32-pin VFQFN
package that is optimum for applications with space limitations.
Features
• Three banks of outputs:
Bank A: three single-ended LVCMOS/LVTTL outputs at 25MHz
or 50MHz
Bank B: three single-ended LVCMOS/LVTTL outputs at 125MHz
Bank C: three differential LVDS outputs at 125MHz
Reference LVCMOS/LVTTL output at 25MHz
• Crystal input frequency: 25MHz
• Maximum output frequency: 125MHz
• RMS phase jitter @ 125MHz, using a 25MHz crystal
(637kHz - 62.5MHz): 0.373ps (typical) LVDS output
• RMS phase jitter @ 25MHz, using a 25MHz crystal
(12kHz - 1MHz): 0.64ps (typical) LVCMOS output
• Full 3.3V supply mode
• -40°C to 85°C ambient operating temperature
• Available in lead-free (RoHS 6) package
