Utilizing an innovative Adaptive Differential Phase Shift Keying (ADPSK) modulation scheme and Fujitsu patented Variable Dispersion Compensation (VDC), the second generation units enable network growth up to 1.
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.
Though new methods such as duo binary module and Differential Phase Shift Keying (DPSK) that are strong in relation to dispersion are being developed, they require driver ICs with higher output amplitude since the modulator is driven with higher voltage than conventional ones.
