LVDS/LVCMOS CLOCK GENERATOR 1 ICS8402010AKI REV. A AUGUST 28, 2008
GENERAL DESCRIPTION
ICS8402010I is a low phase noise Clock Generator
and is a member of the HiperClockS™ family of high
performance clock solutions from IDT. The device
provides three banks of outputs and a reference
clock. Each bank can be independently enabled by
using output enable pins. A 25MHz, 18pF parallel resonant
crystal is used to generate the 16.66MHz, 62.5MHz and 25MHz
frequencies. The typical RMS phase jitter for this device is less
than 1ps.
FEATURES
• Three banks of outputs:
Bank A/B: three single-ended LVCMOS outputs at 16.66MHz
Bank C: three differential LVDS outputs at 62.5MHz
One single-ended reference clock output at 25MHz
• Crystal input frequency: 25MHz
• Maximum output frequency: 62.5MHz
• RMS phase jitter @ 62.5MHz, using a 25MHz crystal,
Integration Range (1.875MHz - 20MHz): 0.375ps (typical)
• Full 3.3V operating supply
• -40°C to 85°C ambient operating temperature
• Available in both standard (RoHS 5) and lead-free (RoHS6)
