GENERAL DESCRIPTION

FEATURES

The ICS8432-111 is a general purpose, dual out- • Dual differential 3.3V LVPECL outputs

ICS

put Differential-to-3.3V LVPECL High Frequency

• Selectable differential CLK, nCLK pair or LVCMOSTEST_CLK

HiPerClockS™

Synthesizer and a member of the HiPerClockS™

family of High Performance Clocks Solutions

from ICS. The ICS8432-111 has a selectable

• CLK, nCLK pair can accept the following differential input

levels: LVPECL, LVDS, LVHSTL, SSTL, HCSL

differential CLK, nCLK pair or LVCMOS/LVTTLTEST_CLK.The

TEST_CLK input accepts LVCMOS or LVTTL input levels

and translates them to 3.3V LVPECL levels. The CLK, nCLK

pair can accept most standard differential input levels.The

VCO operates at a frequency range of 200MHz to 700MHz.

The VCO frequency is programmed in steps equal to the value

of the input differential or single ended reference frequency.

Output frequencies up to 700MHz for FOUT and 350MHz for

FOUT/2 can be programmed using the serial or parallel

interfaces to the configuration logic. The low phase noise

characteristics and the multiple frequency outputs of the

ICS8432-111 makes it an ideal clock source for Fibre Channel

1 and 2, and Infiniband applications.

• TEST_CLK can accept the following input types:

LVCMOS or LVTTL

• Maximum FOUT frequency: 700MHz

Maximum FOUT/2 frequency: 350MHz

• CLK, nCLK or TEST_CLK input frequency: 40MHz

• VCO range: 250MHz to 700MHz

• Parallel or serial interface for programming counter

andVCO frequency multiplier and dividers

• RMS period jitter: 5ps (maximum)

• Cycle-to-cycle jitter: 40ps (maximum)

• 3.3V supply voltage

• 0°C to 70°C ambient operating temperature
