5G and IoT Supplement
Hittite Microwave will introduce the HMC700LP4E, the first in a new series of integrated fractional-N synthesizers designed to cover a wide range of applications particularly those sensitive to phase noise and signal jitter. This innovative fractional-N synthesizer features a 16 bit fractional divider, 24 bit delta-sigma modulator, 14 bit reference path divider, ultra low noise phase frequency detector (PFD), a precision controlled charge pump and extensive access to various modes of operation via a read/writable serial port.
This designer friendly product delivers typical phase noise performance of -103 dBc/Hz in fractional mode at 6 GHz and 20 kHz offset, translating to a Figure of Merit (FOM) of -223 dBc. Integer operation at 6 GHz can achieve -108 dBc/Hz at 20 kHz offset with a FOM of -227 dBc. Typical VCO step resolution is 3 Hz with a 50 MHz PFD in fractional mode. Reference spurious levels are <-130 dBc and in-band fractional boundary spurious are typically well below the integrated phase noise.
