350MHZ, CRYSTAL-TO-LVCMOS/LVTTL

FREQUENCY SYNTHESIZER

ICS8402I

General Description

Features

The ICS8402I is a general purpose,

• Two LVCMOS/LVTTL outputs

Crystal-to-LVCMOS/LVTTL High Frequency

Synthesizer and a member of the HiPerClockS™

family of High Performance Clock Solutions from

IDT. The ICS8402I has a selectable TEST_CLK or

• Selectable crystal oscillator interface or LVCMOS/LVTTL

HiPerClockS™

TEST_CLK

• Output frequency range: 15.625MHz to 350MHz

• Crystal input frequency range: 12MHz to 40MHz

• VCO range: 250MHz to 700MHz

crystal inputs. The VCO operates at a frequency range of 250MHz

to 700MHz. 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. The low phase noise

characteristics of the ICS8402I make it an ideal clock source for

Gigabit Ethernet and SONET applications.

• Parallel or serial interface for programming counter and

output dividers

• RMS period jitter: 30ps (maximum)

• Cycle-to-cycle jitter: 100ps (maximum)

• Full 3.3V or mixed 3.3V core/2.5V output supply

• -40°C to 85°C ambient operating temperature

• Available in both standard (RoHS 5) and lead-free (RoHS 6)
