Description

This frequency synthesizer is designed for sensitive converter applications.  The TLSD synthesizers operate from 1 to 12.5 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.
