700MHZ, DIFFERENTIAL-TO-3.3V

LVPECL FREQUENCY SYNTHESIZER

ICS8432-101

GENERAL DESCRIPTION

FEATURES

The ICS8432-101 is a general purpose, dual out-

• Dual differential 3.3V LVPECL outputs

ICS

HiPerClockS™

put Differential-to-3.3V LVPECL high frequency

• Selectable CLK, nCLK or LVCMOS/LVTTL TEST_CLK

synthesizer and a member of the HiPerClockS™

family of High Performance Clock Solutions from

ICS.The ICS8432-101 has a selectable TEST_CLK

• TEST_CLK can accept the following input levels:

LVCMOS or LVTTL

or CLK, nCLK inputs. The TEST_CLK input accepts LVCMOS

or LVTTL input levels and translates them to 3.3V LVPECL lev-

els. The CLK, nCLK pair can accept most standard differen-

tial input levels. 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 differential or single ended

reference frequency. The VCO and output frequency can be

programmed using the serial or parallel interfaces to the con-

figuration logic. The low phase noise characteristics of the

ICS8432-101 makes it an ideal clock source for Gigabit Ethernet

and SONET applications.

• CLK, nCLK pair can accept the following differential

input levels: LVPECL, LVDS, LVHSTL, SSTL, HCSL

• CLK, nCLK or TEST_CLK maximum input frequency: 40MHz

• Output frequency range: 25MHz to 700MHz

• VCO range: 250MHz to 700MHz

• Accepts any single-ended input signal on CLK input with

resistor bias on nCLK input

• Parallel interface for programming counter and output

dividers

• RMS period jitter: 5ps (maximum)

• Cycle-to-cycle jitter: 25ps (maximum)

• 3.3V supply voltage

• 0°C to 70°C ambient operating temperature

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