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.

Block Diagram
Description
The TLS is an advanced frequency synthesizer design using a unique triple loop architecture in a miniature low profile package that offers either a serial RS485 or parallel frequency control.
This unit is ideal for applications requiring more demanding phase noise, spectral purity and resolution requirements then are offered by a single phase-locked loop frequency synthesizer configuration.
These units are easily customized to specific requirements and offer a great performance to cost factor. |

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. |
