Getting the Jitter Out - High Speed Communications Timing Technology
High-speed digital communications have been adopted so quickly because of a variety of performance advantages. The signals are quantized and may be encoded, making them less susceptible to noise and interference, which also increases the acceptable transmit range. Complex modulation schemes increase spectral efficiency, allowing for higher data rates and errors can be detected and corrected with processing. However, these communications networks must accurately reconstruct the sampled incoming signal, making timing synchronization critically important. This eBook focuses on jitter, simply defined as any effect that causes signal threshold crossing times to deviate from their expected positions. The first article addresses the inter-relationships between jitter and other noise-generating mechanisms. The second explains the types and sources of jitter and the third looks at how jitter propagates through the channel. The final six articles in this eBook show Skyworks’ broad portfolio of frequency flexible timing products along with how they compare to and can be incorporated with solutions from six different suppliers.
