The ADC32RF8x (ADC32RF80 and ADC32RF83) is a 14-bit, 3-GSPS, dual-channel telecom receiver and feedback device family that supports RF sampling with input frequencies up to 4 GHz and beyond. 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).

FREQ-DDC-FILTER-CALC — RF-Sampling Frequency Planner, Analog Filter, and DDC Excel Calculator

這個 Excel 計算機為系統設計人員提供了一種簡化直接 RF 取樣接收器設計和偵錯的方法。它提供了三項功能:頻率規劃、類比濾波和降頻濾波器雜散定位

在概念階段,頻率規劃工具能夠精確調整 ADC 取樣率和輸入頻率位置,以在阻塞事件期間最佳化無雜散動態範圍 (SFDR)。某些設計在這兩方面都具有靈活性;而其他一些設計,例如 L 波段接收器或無線基礎設施基地台,則處理固定頻帶,僅提供取樣率調整功能。

外部 RF 濾波器回應高度依賴於系統 SFDR 目標與 ADC 本身的 SFDR 性能;類比濾波器工具可在設計階段提供協助。
