【文字介紹】

ADV7281/ADV7281-M/ADV7281-MA是功能豐富的單晶片、多格式視頻解碼器。ADV7281/ ADV7281-M/ADV7281-MA可自動檢測標準模擬基帶視訊訊號,相容複合、S視頻和分量視頻形式的NTSC、PAL和SECAM全球標準信號。
ADV7281可將類比視訊訊號轉換為YCrCb 4:2:2視頻資料流程,其與8位ITU-R BT.656介面標準相容。
ADV7281-M/ADV7281-MA可將類比視訊訊號轉換為8位、YCrCb 4:2:2視頻資料流程,可通過相容移動工業處理器介面(MIPI®)的 CSI-2介面輸出。
ADV7281/ADV7281-M/ ADV7281-MA的類比視頻輸入端支援單端、偽差分和全差分信號。ADV7281提供4路類比輸入信號和2個STB診斷引腳。ADV7281-M提供6路模擬輸入、2個STB診斷引腳和3路通用輸出。ADV7281-MA提供8路模擬輸入和3路通用輸出。
ADV7281/ADV7281-M/ADV7281-MA通過雙線式串列雙向埠(I2C相容型)進行程式設計,並且採用1.8 V CMOS工藝製造。該解碼器提供LFCSP封裝選項,非常適合空間受限的可擕式應用。
