General Description

The LMX2370 monolithic, integrated dual frequency synthesizer, including prescalers, is designed to be used as a first and second local oscillator for dual mode or dual conversion transceivers. It is fabricated using National's 0.5u ABiCV silicon BiCMOS process. The LMX2370 contains two dual modulus prescalers. A 32/33 or a 16/17 prescaler can be selected for the Main synthesizer and a 16/17 or 8/9 prescaler can be selected for the Aux synthesizer. Using a digital phase locked loop technique, the LMX2370 generates very stable, low noise control signals for UHF and VHF voltage controlled oscillators (VCOs). Serial data is transferred into the LMX2370 via a 1.8 V three wire interface (Data, Enable, Clock) compatible with low voltage baseband processors. Supply voltage can range from 2.7V to 5.5V. The LMX2370 features very low current consumption typically: - 6.0 mA at 3V.

The LMX2370 is available in a 24-pad chip scale (CSP), 24-pad thin chip scale (TCSP) or 20-pin TSSOP surface mount plastic packages.

Features

  • 2.7V-5.5V operation
  • Ultra low current consumption
  • Low phase detector noise floor
  • Low voltage MICROWIRE™ interface (1.8V up to VCC)
  • Low prescaler values 32/33 at fIN <= 2.5 GHz 16/17 at fIN <= 1.2 GHz
  • Selectable charge pump current levels
  • Selectable FastLock™ mode
  • Enhanced ESD protection
  • Available in small 24-pad chip scale package (3.5 x 4.5 x 1.0 mm)
  • Available in small 24-pad chip thin scale package (3.5 x 4.5 x 0.8 mm)

Applications

  • Portable wireless communications (PCS/PCN, cordless)
  • Dual mode cellular telephone systems
  • Spread spectrum communication systems (CDMA)
  • Cable TV tuners (CATV)
