Product Details

The ADF4371 allows implementation of fractional-N or integer-N phase-locked loop (PLL) frequency synthesizers when used with an external loop filter and an external reference frequency. The wideband microwave VCO design allows frequencies from 62.5 MHz to 32 GHz to be generated.

The ADF4371 has an integrated VCO with a fundamental output frequency ranging from 4000 MHz to 8000 MHz In addition, the VCO frequency is connected to divide by 1, 2, 4, 8, 16, 32, or 64 circuits that allow the user to generate RF output frequencies as low as 62.5 MHz at RF8. A frequency multiplier at RF16 generates from 8 – 16 GHz. A frequency quadrupler generates frequencies from 16- 32 GHz at RF32. RF4_16 duplicates the frequency range of RF8, or permits direct access to the VCO Output. To suppress the unwanted products of frequency multiplication, a harmonic filter exists between the multipliers and the output stages of RF16 and RF32.

Control of all on-chip registers is through a simple 3-wire interface. The ADF4371 operates with analog and digital power supplies ranging from 3.15 V to 3.45 V, and +5V for the VCO power supply. The ADF4371 also contains hardware and software power-down modes.

Applications

  • Wireless infrastructure (MC-GSM, 5G)
