SFS0990C-LF

Frequency Synthesizer by Z-COMM

Note : Your request will be directed to Z-COMM.

The SFS0990C-LF from Z-Communications is a pre-programmed Fixed Frequency Synthesizer that is phase locked at 990 MHz to an external 10 MHz reference oscillator. This PLL features an exceptionally low phase noise of -119 dBc/Hz at 10 kHz, -100 dBc/Hz at 1 kHz, and -141 dBc/Hz at 100 kHz offsets. It delivers an output power of +1 dBm and requires a supply voltage of 5 Vdc while drawing 25 mA of current and a phase locked loop voltage of 3 Vdc while drawing 14 mA of current. It has a 2nd harmonic suppression of -12 dBc and spurious suppression of -70 dBc. The PLL is available as tape and reel in a PLL-V12C package that measures 0.6 in. x 0.6 in. x 0.22 in. It is ideal for base station, mobile radios, and satellite communication applications.
