Description
  The Luff SLSM models are advanced technology single phase-locked loop frequency synthesizer designs. These are self contained system level components. These units offer excellent performance for many applications.
  In this basic architecture, a tradeoff between frequency resolution and phase noise performance needs to be made. These units are packaged in a miniature connectorized housing. The designs offer flexibility and easy customization for your specific requirement.

Triple loop synthesizers (the new TLSD) that feature:
  Output frequencies up to 12 GHz direct and 24 GHz with an X2 multiplier
  Low phase noise, low microphonics and no phase hits (over temperature)
  Low spurious
  All standard interface options selectable within the unit (RS232, RS422, RS485)
  Multi drop bus configurations
  Reference Frequency: 1, 5, 10, or 20 MHz or Internal ref (±1PPM)
  Rugged EMI shielded enclosure
Model: TLSD


Description
  This frequency synthesizer is designed for sensitive converter applications.  The TLSD units operate from 1 to 12 GHz (in bands) and can cover in excess of octave bandwidths. The spectral quality is excellent, typically better than -90 dBc/Hz at X-band @10 kHz off the carrier.
  This design is extremely flexible, providing customer selectable interfaces of RS232, RS422 and RS485.  There is also a provision for multiple units on one buss.  Operating several units within one draw is possible because the unit offers a multi-drop bus configuration.  The units are housed in an EMI enclosure with filtered connectors for minimum radiation and interference.
  This low cost frequency synthesizer offers high performance in a unit with proven quality and reliability.
