TLK100 Ethernet PHY Transformerless Operation

The TLK100 is a single-port Ethernet PHY for 10BaseT and 100Base TX signaling. This application report describes a method for using Texas Instruments Ethernet PHY products without a transformer. A transformerless mode has great benefit in the following scenarios: nontypical applications that are sensitive to cost; short-distance, PCB connections (compromises... [Read more]

Clock jitter analyzed in the time domain

Part 1 of this three-part article series focused on how to accurately estimate jitter from a clock source and combine it with the aperture jitter of an ADC. In this article, Part 2, that combined jitter will be used to calculate the ADC’s signal-to-noise ratio (SNR), which will then be compared against actual measurements.

Clock Solution for High-Speed ADCs

This application report highlights the limiting agents associated with the clock source that adversely affect the ADC signal-to-noise performance. The performance of the ADS5527 ADC clocked with the CDCE62005 is shown and compared to ideal baseline performance. Additional improvement topologies are presented, along with measured results that show the... [Read more]
