DATA SHEET

GENERAL DESCRIPTION

FEATURES

The 843034I-06 is a general purpose, low phase noise LVPECL

synthesizer which can generate frequencies for a wide variety of

applications.The 843034I-06 has a 4:1 input multiplexer from which

the following inputs can be selected: one differential input, one

single-ended input, or one of two crystal oscillators, thus making the

device ideal for frequency translation or frequency generation.The

843034I-06 has dual LVPECL outputs that may be programmed for

÷2, ÷4 or ÷5 of the VCO frequency. The 843034I-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.

• Dual differential 3.3V LVPECL outputs

• 4:1 Input Mux:

One differential input

One single-ended input

Two crystal oscillator interfaces

• CLK, nCLK pair can accept the following differential

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

• Output frequency range: 120MHz to 375MHz

• Crystal input frequency range: 12MHz to 40MHz

• VCO range: 600MHz to 750MHz

• Supports Spread Spectrum Clocking (SSC)

• Parallel or serial interface for programming feedback divider

and output dividers

• RMS phase jitter at 166.6MHz, using a 22.222MHz crystal

(12kHz to 30MHz): 1.33ps (typical), SSC - Off

• 3.3V supply mode

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

• Available in lead-free (RoHS 6) package

• Use functional replacement part 8t49N241-dddNLGI
