ICS8442I-90 - Crystal-to-LVDS Frequency Synthesizer

General Description

The ICS8442I-90 is a general purpose, dual output Crystal-to-Differential LVDS High Frequency Synthesizer.

The ICS8442I-90 has a selectable REF_CLK or crystal input.

The REF_CLK input accepts LVCMOS or LVTTL input levels and translates them to LVDS levels.

Key Features

  • Dual differential LVDS outputs FOUT1/nFOUT1 lags FOUT0/nFOUT0 by 90°.
  • Selectable crystal oscillator interface or LVCMOS/LVTTL REF_CLK.
  • Output frequency range: 31.25MHz.
  • 700MHz.
  • Crystal input frequency range: 10MHz to 25MHz.
  • VCO range: 250MHz.
  • 700MHz.
  • Parallel or serial interface for programming counter and output dividers.
  • RMS period jitter: 7ps (maximum), (N= ÷1, ÷2, ÷4).
  • Cycle-to-cycle jitter: 34ps (maxi.

700MHz, Crystal-to-LVDS Frequency Synthesizer PRODUCT DISCONTINUATION NOTICE - LAST TIME BUY EXPIRES JANUARY 27, 2015 ICS8442I-90 DATA SHEET General Description The ICS8442I-90 is a general purpose, dual output Crystal-to-Differential LVDS High Frequency Synthesizer. The ICS8442I-90 has a selectable REF_CLK or crystal input. The REF_CLK input accepts LVCMOS or LVTTL input levels and translates them to LVDS 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 reference or crystal frequency. The VCO and output frequency can be programmed using the serial or parallel interface to the configuration logic.
