LUCY SDR （新的SDR接收機(jī)方案，文章轉(zhuǎn)自網(wǎng)絡(luò)，原文作者SO5WI）
Hello folks!
This is my first blogpost here. And i am about to introduce you ADC board based on BBRF103 (https://sdr-prototypes.blogspot.com/) idea. This board is a part of Lucy SDR solution which is (would be) 0.05-3GHz software receiver with 50MHz of visible spectrum.
It is based on LTC2217 ADC with 105MSPS sampling rate and Cypress FX3 bridge to transfer 16bit samples to PC. You might take a look on chematic below to see how this looks. At the beginning you have 50MHz LPF. Also the LTC is driven from SI5350 which in further releases will receive stable 10MHz GPS input and will drive PLL for frequency mixer.
Everything would be finally released as an open source solution.

大家好！
這是我在這里的第一篇博文。我將向大家介紹基于BBRF103?(https://sdr-prototypes.blogspot.com/)?的想法。這塊板是LUCY?SDR解決方案的一部分，這是0.05 - 3GHz軟件接收機(jī)與50MHz的可見光譜。
它是基于具有105msps采樣率的ltc2217adc和cypress fx3向pc機(jī)傳輸16位樣本。您可能會(huì)看看下面的chematic看看這看起來如何。一開始你有50兆赫的lpf。此外，ltc是從si5350驅(qū)動(dòng)，在進(jìn)一步的版本將收到穩(wěn)定的10mhz gps輸入，并將驅(qū)動(dòng)鎖相環(huán)頻率混頻器。
一切最終都將作為開源解決方案發(fā)布。
