Exposing the hidden costs of using off-the-shelf analog ICs
Design How-To  
7/4/2011   11 comments
There are many standard analog chips in the market that are simply priced too high. It may make good economic sense to consider using an analog ASIC company developed a chip that mimics a standard product.

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.
