ICS84320-01

780MHZ, CRYSTAL-TO-3.3V DIFFERENTIAL

LVPECL FREQUENCY SYNTHESIZER

GENERAL DESCRIPTION

FEATURES

The ICS84320-01 is a general purpose, dual out- • Dual differential 3.3V LVPECL outputs

ICS

HiPerClockS™

put Crystal-to-3.3V Differential LVPECL High Fre-

quency Synthesizer and a member of the

HiPerClockS™ family of High Performance Clock

Solutions from IDT. The ICS84320-01 has a se-

• Selectable crystal oscillator interface

or LVCMOS/LVTTL TEST_CLK

• Output frequency range: 77.5MHz to 780MHz

• Crystal input frequency range: 14MHz to 40MHz

• VCO range: 620MHz to 780MHz

lectable TEST_CLK or crystal inputs. The VCO operates at a

frequency range of 620MHz to 780MHz. The VCO frequency

is programmed in steps equal to the value of the input refer-

ence 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 ICS84320-01 make it an ideal clock source for 10 Gigabit

Ethernet, SONET, and Serial Attached SCSI applications.

• Parallel or serial interface for programming counter

and output dividers

• Duty cycle: 49% - 51% (N > 1)

• RMS period jitter: 2ps (typical)

• RMS phase jitter at 155.52MHz, using a 38.88MHz crystal

(12kHz to 20MHz): 2.5ps (typical)

Offset

• 3.3V supply voltage

• 0°C to 70°C ambient operating temperature

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