]本文介紹了如何利用CPLD(復(fù)雜可編程邏輯器件)與單片機(jī)的結(jié)合實(shí)現(xiàn)并行I／\r\nO(輸入／輸出)接口的擴(kuò)展。該設(shè)計(jì)與用8255做并行I／O接口相比，與單片機(jī)軟件完全兼容，\r\n同時(shí)擁有速度快，功耗低，價(jià)格便宜，使用靈活等特點(diǎn)

Dongle泛指任何能插到電腦上的小型硬體，PC TV dongle則是用來(lái)在PC上觀看電視節(jié)目所用的擴(kuò)充裝置。一般來(lái)說(shuō)，依照採(cǎi)用的電視訊號(hào)規(guī)格，PC TV dongle可區(qū)分成兩大類：若使用的訊源為數(shù)位訊號(hào)，則屬於數(shù)位PC TV dongle；若使用的是類比訊號(hào)，則屬於類比PC TV dongle。全球各地皆有不同的採(cǎi)納階段，且推行的廣播標(biāo)準(zhǔn)也不盡相同。

Recent advances in low voltage silicon germaniumand BiCMOS processes have allowed the design andproduction of very high speed amplifi ers. Because theprocesses are low voltage, most of the amplifi er designshave incorporated differential inputs and outputs to regainand maximize total output signal swing. Since many lowvoltageapplications are single-ended, the questions arise,“How can I use a differential I/O amplifi er in a single-endedapplication?” and “What are the implications of suchuse?” This Design Note addresses some of the practicalimplications and demonstrates specifi c single-endedapplications using the 3GHz gain-bandwidth LTC6406differential I/O amplifi er.
