Renesas Electronics debut 8V97003 wideband mmWave synthesizer aimed at 5G and broadband wireless applications

Renesas Electronics introduced a next-generation wideband mmWave synthesizer with high performance and a set of features optimized for 5G and broadband wireless applications. The 8V97003 device is ideal as a local oscillator (LO) for mmWave and beamforming, or a precision reference clock for a high-speed data converter in numerous applications such as test and measurements, optical networking, and data acquisition.

The 8V97003 delivers ideal combination of wide frequency range (171.875 MHz to 18 GHz), ultra-low output phase noise (-60.6dBc at 20 kHz to 100 MHz at 6 GHz) and high output power over its entire frequency range. 

The wide frequency range enables customers to use a single 8V97003 in place of multiple synthesizer modules reducing solution footprint and cost. High output power has eliminated the need for external driver further reducing complexity and overall power consumption without compromising performances. 

The ultra-low output phase noise makes it an excellent choice for 5G and other wireless applications as it enables superior system level signal-to-noise ratio (SNR) and error vector magnitude (EVM). As a reference clock for high-speed data converters, 8V97003 maximizes system performance by improving SNR and spurious-free-dynamic-range (SFDR).

The 8V97003 is a high-performance wideband microwave Synthesizer / Phase Lock Loop (PLL) that generates output frequencies up to 18GHz from an integrated Voltage Controlled Oscillator (VCO) offering an octave of frequency tuning range. The device offers a high-performance 32-bit fractional feedback divider and an output divider to allow users to fully benefit from the wideband characteristics of the VCO. 

The device’s figure of merit (FOM) of -236dBc/Hz and the excellent VCO performance allow for very low phase noise and RMS phase jitter. The 8V97003 offers a very low output-to-output phase skew drift of <10° across all operating conditions and frequencies, reducing radio path recalibration occurrences in beamforming applications, such as 5G radio card massive MIMO systems. 

The output drivers have programmable output power settings and can deliver high single-ended output power up of +12dBm at 8GHz, and +4dBm at 18GHz, when using inductively loaded output terminations (double termination). 

When the outputs are resistively loaded, the output drivers can deliver a single-ended output power of +9.5dBm at 8GHz, and up to -2.5dBm at 12GHz. The output power can be further increased when using differential outputs and measuring the output power differentially. The 8V97003 relies on a single 3.3V power supply and offers low noise integrated LDOs for excellent power supply noise immunity.

“We developed our new 8V97003 for the latest generation of high-performance mmWave radios, ensuring it meets our customers’ most demanding frequency range, phase noise, and output power requirements,” said Bobby Matinpour, vice president of Timing Products, IoT and Infrastructure Business Unit at Renesas. “With its best-in-class performance in a single-chip design, the 8V97003 is particularly well-suited for emerging applications above the 6 GHz carrier frequency, including broadband wireless, microwave backhaul, and 5G radios.”

Mass production quantities of the 8V97003 are available now in a 7mm x 7mm, 48-lead VFQFPN package.
