Local oscillator and GHz clocks requirements in radio applications systems with LMX2594


Specifications: Local oscillator and GHz clocks requirements in radio systems with LMX2594 part 2


2017年 4月 29日

Summary of the complete training (5 videos):

This video is the second part on the specifications of a signal source: Spurs and lock time.

This training is discussing the key requirements of local oscillator in microwave/RF and GHz clocks in  radio applications. The topics covered will establish the key relationships between the requirements of a signal source and their impact in a radio system. After this training, you will be armed with the ability to understand the system requirements of your customer and how they pertain to a signal source so you can engage with your customer in a very meaningful way. We will make  clear simple links between phase noise and error vector magnitude (EVM) / reciprocal mixing, spurs and undesired responses, Jitter and SNR / noise figure, Synchronization and coherent receivers / phase array antenna, Sysref and deterministic latency. LMX2594 is a high performance signal source targeted at these applications with purpose built features.
