LUCY SDR （新的SDR接收机方案，文章转自网络，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！

这是我在这里的第一篇博文。我将向大家介绍基于BBRF103 (https://sdr-prototypes.blogspot.com/) 的想法。这块板是LUCY SDR解决方案的一部分，这是0.05 - 3GHz软件接收机与50MHz的可见光谱。

它是基于具有105msps采样率的ltc2217adc和cypress fx3向pc机传输16位样本。您可能会看看下面的chematic看看这看起来如何。一开始你有50兆赫的lpf。此外，ltc是从si5350驱动，在进一步的版本将收到稳定的10mhz gps输入，并将驱动锁相环频率混频器。

一切最终都将作为开源解决方案发布。
