With 1.8-GHz carrier open-loop VCO phase noise of -144.5 dBc/Hz at a 1-MHz offset, the LMX2582 is one of the first PLLs with an integrated VCO to meet the multicarrier wireless GSM communication ...

The ADF4371 synthesizer from Analog Devices offers a wide continuous RF output range of 62 MHz to 32 GHz and an ultra-low normalized phase noise floor (FOM) of -234 dBc/Hz. Consisting of a PLL with ...

The performance is achieved by the ADF4377 synthesizer delivering jitter levels below 18fs rms as a consequence of the low normalised in-band phase noise at -239dBc/Hz, -147dBc/Hz normalised 1/f noise ...

Analog Devices is aiming at basestations with a phased-locked loop (PLL) synthesiser with integrated voltage-controlled oscillator (VCO). Called ADF4355, typical phase noise is -144dBc/Hz (1MHz offset ...

Enables new levels of integration and performance for multi-standard single chip ICs Ottawa, ON – April 3, 2006 – Kaben Research Inc., a leading developer of mixed-signal, Intellectual Property (IP) ...

Low-phase-noise microwave oscillators are important to a wide range of subjects, including communications, radar and metrology. Photonic-based microwave-wave sources now provide record, close-to ...

Texas Instruments has introduced a wideband frequency synthesizer with integrated voltage-controlled oscillator (VCO) that delivers the industry’s lowest phase noise. Key specification and features: ...

Figure 5. Integer-N, ADF4106 with VCO-1901846T. Figure 6. Fractional-N, ADF4153A with VCO-1901846T. The ability to increase PFD frequency and frequency resolution was accompanied by improvements to ...

Analog Devices (ADI) has introduced an 800MHz to 12.8GHz synthesizer for high performance ultra-wideband data converter and synchronisation applications. The ADF4377 synthesizer enables excellent ...

Last session, we use the cheap and cheerful 4046 Phase-locked Loop chip as a simple voltage-controlled oscillator (VCO). It was dead simple, in fact, because the chip has a VCO already built in. Th… ...
