Jitter and timing analysis in the presence of crosstalk Design How-To 12/14/2011 3 comments Serial data standards continue to proliferate, providing dramatic improvements in PC and Server system performance. Testing these higher speed standards for evidence of jitter is critical for long-term stability and to achieving the objective of a good Bit Error Ratio (BER) in the design. Effective analysis begins with selecting the right instruments and have a good understanding of instrument noise, rise time and factors such 3rd, 4th, 5th harmonic performance.
Defining the 4G PHY architecture design challenges Design How-To 12/5/2011 2 comments As with most emerging technologies, design challenges for LTE-A abound, particularly when it comes to the physical layer (PHY) architecture development. Addressing these challenges remains critical to the successful development and deployment of LTE-A designs.
