According to the company, the wideband ADC12DJ3200 is the fastest 12bit A/D converter, delivering speeds up to 6.4Gsample/s. The LMX2594 is said to be the first wideband PLL solution to generate frequencies of up to 15GHz without using an internal frequency doubler.
The ADC12DJ3200 and LMX2594 provide accurate, time-stable synchronisation for multi-node sampling systems including large-scale phased-array radars, digital storage oscilloscopes and 5G wireless testers.
The ADC12DJ3200 A/D converter features direct RF sampling of up to 10GHz covering the L-band, S-band and C-band and extending into the X-band. The 10 x 10mm device integrates an entire RF-to-bits receiver, reducing board space by up to 88%. Consuming 3W, the company claims the A/D converter provides twice the input frequency range at half the power of competing devices.
The LMX2594 RF PLL with VCO is said to make it easier for engineers to design a high frequency RF signal chain. It features a normalised PLL noise floor of -236dBc/Hz and 1/f of -129dBc/Hz, enabling designers to improve radio sensitivity and spectral resolution.
The integrated VCO operates at up to 15GHz, eliminating the need for expensive, complex on-board filters to remove subharmonics. The LMX2594 also automatically generates a frequency ramp, eliminating up to five devices typically required to perform this function.
System designers can synchronise the output of all on-board PLLs, saving design time for implementing multiple-input/multiple-output, beamforming in their applications.
The LMX2594 enables simultaneous generation of gigahertz frequency sampling and JESD204B SYSREF timing signals.
