500MHz, Crystal-to-3.3V, 2.5V

Differential LVPECL Frequency Synthesizer

DATASHEET

General Description

Features

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

• Dual differential 3.3V or 2.5V LVPECL outputs

• Selectable crystal oscillator interface or LVCMOS/LVTTL

HiPerClockS™

REF_CLK

• Output frequency range: 20.83MHz to 500MHz

• Crystal input frequency range: 14MHz to 27MHz

• VCO range: 250MHz to 500MHz

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.

• 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)
