snaa360 application note | 德州仪器 ti.com.cn-九游会棋牌

getting the most out of a rf signal chain design partly depends on providing a low phase noise, clean clock to the a/d converter. in this application report, phase noise data taken using the texas instruments’ lmx1204 clock distribution device is studied. in general, the phase noise performance of any clock distribution method, is not only dependent upon the phase noise of the input clock source, but also the active clock signal chain as well. in this case the lmx1204 will be studied in both single and cascaded configurations. in general, the performance measurements confirm the operational ability of the lmx1204 device to provide as an adequate distribution method, up to 16 channels, with minimal degradation in converter performance.
