Z-Communications, Inc. announces a new Fixed Frequency Synthesizer model SFS0990C-LF. The SFS0990C-LF is a preprogrammed synthesizer that is phase locked at 990MHz to an external 10MHz reference oscillator. This PLL features an exceptionally low typical phase noise of -119dBc/Hz at 10kHz, -100dBc/Hz at 1kHz, and -141dBc/Hz at 100kHz offsets.

The RoHS compliant SFS0990C-LF is designed to deliver a typical output power of +1dBm while operating off a VCO voltage supply of 5Vdc and drawing 25mA (typical) and a phase locked loop voltage of 3Vdc while drawing 14mA (typical). This Fixed Frequency Synthesizer features a typical 2nd harmonic suppression of -12dBc and spurious suppression of -70dBc. It is housed in Z-COMM’s standard PLL-V12C package measuring 0.6 in. x 0.6 in. x 0.22 in. The SFS0990C-LF is also ideal for automated surface mount assembly and is available in tape and reel packaging.

SFS0990C-LF is an excellent choice for basestations, mobile radios, and satellite communication applications which require quick and simple integration while demanding high performance over the industrial temperature range of -30 to 85°C.
