mmWave synthesiser chip covers 172MHz – 18GHz

“We developed our 8V97003 for mmWave radios, ensuring it meets demanding frequency range, phase noise, and output power requirements,” said Renesas v-p of timing products Bobby Matinpour. “8V97003 is particularly well-suited for emerging applications above the 6GHz carrier frequency, including broadband wireless, microwave back-haul, and 5G radios.”

The company claims a good combination of frequency range and output phase noise: 171.875MHz – 18GHz and -60.6dBc (at 20kHz to 100MHz at 6GHz).

Synthesis is fractional-N and integer-N, with 16bit integer and 32bit fractional resolution.

Input reference is 10MHz to 1.6GHz (LVPECL, LVDS) or 10MHz to 250MHz (LVCMOS). The controlling SPI interface is compatible with 1.8V logic and tolerant to 3.3V.

“The 8V97003 is ideal as a local oscillator for mmWave and beam forming, or a precision reference clock for a high-speed data converter in applications such as test and measurements, optical networking, and data acquisition,” according to the company.

Operation is at 3.3V and over -40°C to +95°C ambient, and up to +105°C case.

The chip is available now in a 7 x 7mm 48-VFQFPN.
