Designed for high signal-to-noise ratio (SNR), the ADC32RF8x family delivers a noise spectral density of –155 dBFS/Hz as well as dynamic range and channel isolation over a large input frequency range. The buffered analog input with on-chip termination provides uniform input impedance across a wide frequency range and minimizes sample-and-hold glitch energy. Each channel can be connected to a dual-band, digital down-converter (DDC) with up to three independent, 16-bit numerically-controlled oscillators (NCOs) per DDC for phase-coherent frequency hopping. Additionally, the ADC is equipped with front- end peak and RMS power detectors and alarm functions to support external automatic gain control (AGC) algorithms. The ADC32RF8x supports the JESD204B serial interface with subclass 1-based deterministic latency using data rates up to 12.5 Gbps with up to four lanes per ADC. The device is offered in a 72-pin VQFN package (10 mm × 10 mm) and supports the industrial temperature range (–40°C to +85°C). Device Information(1) PART NUMBER PACKAGE BODY SIZE (NOM) ADC32RF8x VQFN (72) 10.00 mm × 10.00 mm (1) For all available packages, see the orderable addendum at the end of the data sheet.
