USB JTAG debuggers target ARM, Xscale, PowerPC micros
Product News  
4/1/2006   Post a comment
A pair of inexpensive USB 2.0 JTAG debug interface devices are now available from Macraigor Systems. These devices target ARM, Xscale, and PowerPC microprocessors.

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
