PRELIMINARY  
FEMTOCLOCKS™ MULTI-RATE 3.3V  
LVPECL FREQUENCY SYNTHESIZER  
ICS843034-06  
GENERAL DESCRIPTION  
FEATURES  
The ICS843034-06 is a general purpose, low phase  
• Dual differential 3.3V LVPECL outputs  
ICS  
noise LVPECL synthesizer which can generate  
frequencies for a wide variety of applications. The  
ICS843034-06 has a 4:1 input Multiplexer from  
which the following inputs can be selected: one  
differential input, one single-ended input, or two  
• 4:1 Input Mux:  
HiPerClockS™  
One differential input  
One single-ended input  
Two crystal oscillator interfaces  
crystal oscillators, thus making the device ideal for frequency  
translation or frequency generation. The ICS843034-06 has  
dual LVPECL outputs that may be programmed for ÷2, ÷4 or  
÷5 from the VCO frequency. The ICS843034-06 also supplies  
a buffered copy of the reference clock or crystal frequency on  
the single-ended REF_OUT pin which can be enabled or  
disabled (disabled by default). The output frequency can be  
programmed using either a serial or parallel programming  
interface. This device supports Spread Spectrum Clocking  
(SSC) for EMI reduction.  
• CLK, nCLK pair can accept the following differential  
input levels: LVPECL, LVDS, LVHSTL, HCSL, SSTL  
• REF_CLK accepts LVCMOS or LVTTL input levels  
• Output frequency range: 35MHz to 750MHz  
• Crystal input frequency range: 12MHz to 40MHz  
• VCO range: 560MHz to 750MHz  
• Supports Spread Spectrum Clocking (SSC)  
• Parallel or serial interface for programming feedback divider  
and output dividers  
• RMS phase jitter at 333.33MHz, using a 22.222MHz crystal  
(12kHz to 20MHz): 1.37ps (typical), SSC - Off  
• 3.3V supply mode  
• 0°C to 70°C ambient operating temperature  
• Industrial temperature available upon request

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