General Description

The LMX2346/7 are high performance frequency synthesizers with an integrated 32/33 dual modulus prescaler. The LMX2346 is designed for RF operation up to 2.0 GHz. The LMX2347 is designed for RF operation up to 2.5 GHz. Using a proprietary digital phase locked loop technique, the LMX2346/7 generates very stable, low noise control signals for UHF and VHF voltage controlled oscillators.

Serial data is transferred into the LMX2346/7 via a three-line MICROWIRE interface (DATA, LE, CLOCK). Supply voltage range is from 2.7V to 5.5V. The charge pump provides 4 mA output current.

The LMX2346/7 are manufactured using National's 0.5µ ABiC V silicon BiCMOS process and is available in 16-pin TSSOP and 16-pin CSP packages.

Features

  • RF operation up to 2.5 GHz
  • 2.7V to 5.5V operation
  • Digital & Analog Lock Detect
  • 32/33 Dual modulus prescaler
  • Excellent Phase Noise
  • Internal balanced, low leakage charge pump
  • Pin Compatible to LMX2323

Applications

  • Cellular DCS/PCS/3G infrastructure equipment
  • Wireless Local Area Networks (WLANs)
  • Other wireless communication systems
