500MHz, Crystal-to-3.3V, 2.5V
Differential LVPECL Frequency Synthesizer
ICS8430-62
General Description
The ICS8430-62 is a general purpose, dual output
Crystal-to-3.3V, 2.5V Differential LVPECL High
Frequency Synthesizer and a member of the
HiPerClockS family of High Performance Clock
Solutions from IDT. The ICS8430-62 has a selectable
REF_CLK or crystal inputs. The VCO operates at a frequency range
of 250MHz to 500MHz. The VCO frequency is programmed in steps
equal to the value of the input reference or crystal frequency. The
VCO and output frequency can be programmed using the serial or
parallel interfaces to the configuration logic. Frequency steps as
small as 1MHz can be achieved using a 16MHz crystal or REF_CLK.
Features
Dual differential 3.3V or 2.5V LVPECL outputs
Selectable crystal oscillator interface or LVCMOS/LVTTL
REF_CLK
Output frequency range: 20.83MHz to 500MHz
Crystal input frequency range: 14MHz to 27MHz
VCO range: 250MHz to 500MHz
Parallel or serial interface for programming counter
and output dividers
RMS period jitter: 5ps (maximum)
Cycle-to-cycle jitter: 35ps (maximum)
Full 3.3V or 3.3V core/2.5V output supply
0°C to 70°C ambient operating temperature
Available in both standard (RoHS 5) and lead-free (RoHS 6)
