L-band frequency synthesiser for GPS clock systems
Operating in the L-band at 1575.42MHz with a 10MHz reference, the SFS1575D-LF single fixed frequency synthesiser has been announced by Z-Communications. It is designed to deliver a typical output power of 5dBm with a VCO voltage supply of 5V DC while drawing 20mA (typical) and a phase locked loop voltage of 3V DC while drawing 14mA (typical).
Featuring a typical phase noise of -102dBc/Hz at the 10kHz offset, the fixed frequency synthesiser provides typical 2nd harmonic suppression of -18dBc and spurious suppression of -70dBc. The SFS11800-LF is suitable for GPS clock systems that require extremely low phase noise performance while operating over the industrial temperature range from -40 to +85°C.
Housed in Z-Comm's standard PLL-V12N package measuring 0.6x0.6x0.13", it is also suited to automated surface mount assembly and is available in tape and reel packaging.
