Gbit Ethernet transceiver saves power
Product News  
1/3/2003   Post a comment
Texas Instruments Inc.'s TLK2208 eight-port Gigabit Ethernet transceiver is claimed to lower power consumption to a maximum of 162 milliwatts per channel at 1.25 Gbits/second.

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.
