TI 12-bit ADCs handle up to 900 Msamples/s Product News 6/13/2013 Post a comment Comprising six single-channel and dual-channel models, Texas Instruments’ ADS5409 family of 12 bit ADCs offers sampling speeds ranging from 500 Msamples/s to 900 Msamples/s, while reducing board space requirements by 80%.
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.
