FEMTOCLOCKS CRYSTAL-TO-3.3V LVPECL FREQUENCY
SYNTHESIZER WITH/INTEGRATED FANOUT BUFFER
ICS843256
IDT / ICS 3.3V LVPECL FREQUENCY SYNTHESIZER
1
ICS843256AM REV. A NOVEMBER 15, 2006
PRELIMINARY
GENERAL DESCRIPTION
The ICS843256 is a Crystal-to-3.3V LVPECL Clock
Synthesizer/Fanout Buffer designed for
Fibre
Channel and Gigabit Ethernet applications and is
a member of the HiperClockS family of High
Performance Clock Solutions from IDT. The output
frequency can be set using the frequency select pins and a
25MHz crystal for Ethernet frequencies, or a 19.44MHz crystal
for SONET. The low phase noise character istics of the
ICS843256 make it an ideal clock for these demanding
applications.
FEATURES
Six 3.3V differential LVPECL output pairs
Crystal oscillator interface
Crystal input frequency range: 15.625MHz to 25.5MHz
RMS phase jitter at 125MHz, using a 25MHz crystal
(1.875MHz to 20MHz): 0.33ps (typical)
Full 3.3V or 3.3V core, 2.5V output supply mode
0°C to 70°C ambient operating temperature
Industrial temperature available upon request
Available in both standard (RoHS 5) and lead-free (RoHS 6)
