CMOS Oscillator Features -168 dBc/Hz Noise Floor

In a 5 mm x 7.5 mm package, the CCHD-575 CMOS oscillator specifies a -168 dBc/Hz noise floor and a typical phase jitter of 82 fs rms at 100 MHz. Close-in phase noise is -90 dBc/Hz at 10 Hz while its floor is at -168 dBc/Hz.  The component generates frequencies between 50 MHz and 130 MHz and its output driver is capable of driving ±24 mA, translating to a rise/fall time of 600 ps at 100 MHz with a 15 pF load. Input voltage is 3.3 Vdc power consumption is 15 mA. CRYSTEK CORP., Fort Myers, FL. (800) 237-3061.
