The transmission breakthrough was made possible using the differential phase shift keying (DPSK) method, a new coding scheme for high-capacity communications developed at Bell Labs.
Inphi Corporation's 13650DE and 13651DE, which the company says remain the only stand-alone differential phase shift keying (DPSK) and Duobinary encoders in the industry, are now offered in a 3-by-3 mm QFN plastic package to cut cost and footprint significantly and to provide a measure of compatibility with the company's new 13-series flip flops for use in NRZ applications," said Vince Biancomano, eeProductCenter.
