CMX979 - Dual PLL+VCO

General Description

The CMX979 is a low-power, wideband, dual synthesiser and VCO, supporting signal generation over a wide range of frequencies.

The ‘RF’ high frequency synthesiser employs a Fractional-N design and will operate at up to 3.6GHz using a fully-integrated internal VCO.

Key Features

  • RF synthesiser/PLL Fractional-N 24-bit divider Output range 338MHz.
  • 3.6GHz Programmable output divider Fast lock function Programmable charge pump current.
  • IF synthesiser/PLL Integer-N 14-bit divider Output range 31MHz.
  • 1GHz Programmable output divider.
  • -209dBc/Hz normalised phase noise.
  • Integrated low noise LDO regulator.
  • Flexible power saving operating modes.
  • Single 2.7V to 3.6V supply.
  • 1.8V digital interface supported.
  • -40° to +85° o.
