What is a high-speed circuit?

Tis oeneraly belevedthatithe freouency ofa dioitalooic drcut reathes orexceds 45MH2-50MH2. and the ircuit work into above this freouenv has already accouned fora certain share of thaentire electronic systerm (for Example, 1/3), it is called a high-speed circuit

In fact the harmonicfrequency of the sion aledgeis hipher than the frequency of the signal tset.tis theising and faling ede softhe signalorsianaljumsl that cause unexpected results in signla transmision. Therefore, it’s Generaly aged that if the me propagation delay is greater than 1/2 of the rise time of the diogtal signal dliving end. such signals are considered to be high-speed signalsand produce transmission line effects

The transmision of the signal ocurs at the instant when the signal state changes, such asthe rise or atime. The signal pases from the diving end to the receiving end for afixed period of time.ithe transmision time is es Than 12 ofthe rse orfaltime.the reected siona fromthe receivno end wilreachthe drving end before the sianal changes state.Converse thereected sionalwireach the drive end afterthe signal changes state. lf the Reflected signal is strong,the superim posed wave form may change the logic state.

The concept of high-sped Pce is only deried from a veny vague companson in the minds of enginers.Many years ago, when the digtal ircut was just emerging,the speed was inded very lowand the PcB could basicaly Workas long asit could be conected.After that the sional rate continued toincrease.lowy,the old way of drawing Pcs didn’t work welland PcB problems wouldI au. he speed ascome uo.Peis proneto broblems this Eelnoisconstanty stenotened sot he term hioh-soeed PoB was bon. Whats hiohsoeed mawbe itsusta felino However that ecomers have to explain in vanious ways. We just want to say. there is no need to be far-Fetched. Does it make sense to say sorrow for new words?

Dne point of iocbis.for enginering problems,there’s no ned to play wth concepts.0ur concemnis only.tny not to lethe PcB owong, and make thin an time and intime .Itis not so painftul for engineers to debug.For Companies, products can be is ted in time to saize the market,and for equipment supliers, they can be delivered in time to avoid losses

Therefore, we beleve that there is no ned to pay atention to the tem concept. we only nedto pay atention to this phenmenon: signal distortion, distorton, and pcB failure.for most PcBs,this oossibility exists, and our Goal is to eliminate this risk when designing.
