De-Emphasized Signal Generation with the 81250A ParBERT

Show Description

De-emphasis and equalization are commonly used techniques when transmitting electrical and optical signals at gigabit data rates. The term de-emphasis is used to describe signal conditioning on the transmitter, while the term equalization is used on the receiver side.

De-emphasis and equalization compensate for signal integrity issues caused by the loss in the channel on printed circuit boards, backplanes, and iber optic links. The most popular high-speed electrical standards require transmitter de-emphasis. These standards are: PCI Express®, SATA 3 Gb/s, fully buffered DIMM, CEI, and 10-Gb Ethernet.
