Nkọwa maka DS90UB914A-Q1
Ngwa DS90UB914A-Q1 na-enye interface FPD-Link III nwere ọwa na-ebugharị ọsọ ọsọ yana ọwa njikwa bidirectional maka nnyefe data n'otu eriri coaxial ma ọ bụ ụzọ dị iche.Ngwa DS90UB914A-Q1 na-etinye nrịbama dị iche iche na ma ọwa ihu ọsọ dị elu yana ụzọ data data ọwa njikwa bidirectional.A na-ezubere deserializer maka njikọ dị n'etiti ndị na-ese foto na ndị na-emepụta vidiyo na ECU (Ngalaba njikwa eletrọnịkị).Ngwaọrụ a dabara nke ọma maka ịnya data vidiyo chọrọ ihe ruru 12-bit pixel omimi yana akara mmekọrịta abụọ yana ụgbọ ala njikwa bidirectional.
Deserializer na-egosipụta multiplexer iji kwe ka nhọrọ n'etiti ihe onyonyo ntinye abụọ, otu na-arụ ọrụ n'otu oge.Ụgbọ njem vidiyo bụ isi na-atụgharị data 10-bit ma ọ bụ 12-bit gaa n'otu iyi ọsọ ọsọ dị elu, yana ụgbọ njem njikwa obere latency dị iche iche nke na-anabata ozi njikwa site na ọdụ ụgbọ mmiri I2C ma nweere onwe ya na oge enweghị vidiyo.
Iji teknụzụ elekere agbakwunyere TI na-enye ohere nzikọrịta ozi zuru oke zuru oke n'otu ụzọ dị iche, na-ebu ozi ọwa njikwa asymmetrical-bidirectional.Otu iyi iyi a na-eme ka ọ dị mfe ịnyefe ụgbọ ala data sara mbara n'elu trace PCB na eriri USB site na iwepu nsogbu skew n'etiti data myirịta na ụzọ elekere.Nke a na-echekwa ọnụ ahịa sistemụ nke ukwuu site na ibelata ụzọ data nke na-ebelata PCB n'ígwé, obosara eriri, na nha njikọ na ntụtụ.Na mgbakwunye, ntinye Deserializer na-enye nhazi nhazi iji kwụọ ụgwọ maka mfu sitere na mgbasa ozi n'ebe dị anya.A na-eji ndokọ/ngbanwe ngbanwe nke ime DC iji kwado njikọ njikọ AC jikọtara ọnụ.
