TIDA-01161, 1GHz Signal Bandwidth RF Sampling Receiver Reference Design

Beschreibung

• TIDA-01161, 1GHz Signal Bandwidth RF Sampling Receiver Reference Design. An RF sampling analog-to-digital converter (ADC) operates at a high sampling rate and converts signals directly from radio frequencies (RF) to digital. The reference design features the ADC32RF45 which is a dual channel, 14-bit resolution ADC sampling up to 3GSPS. The maximum signal bandwidth is set by the ADC sampling rate divided by two. With this reference design the signal bandwidth capability exceeds 1GHz. The maximum input frequency is set by the input bandwidth of the input buffers of the ADC and the input transformers. This reference design allows direct capture of RF signals up to 4GHz which is suitable for all of the key telecommunication bands and S-band RADAR applications. The design includes an optimized clocking solution for maintaining the JESD204B serialized data interface and achieving the highest signal-to-noise ratio (SNR) performance
