【文字介紹】

ADV7390/ADV7391/ADV7392/ADV7393均屬於單晶片、高速、數模視訊轉碼器系列。三個2.7 V/3.3 V 10位元視頻DAC支援標清(SD)或高清(HD)視頻格式的複合(CVBS)、S視頻(YC)或分量(YPrPb/RGB)模擬輸出。

這些編碼器針對低功耗操作進行了優化,尺寸極小,並且只需很少的外部器件,非常適合要求電視輸出功能的可擕式和功耗敏感型應用。有線電視信號檢測和DAC自動關斷特性可確保功耗保持最低。

ADV7390/ADV7391配有一個8位元視頻輸入埠,通過SDR介面支援標清視頻格式,通過DDR介面支援高清視頻格式。
ADV7392/ADV7393配有一個16位元視頻輸入埠,可採用多種方式進行配置。同時支援標清RGB輸入。該系列所有器件均支援嵌入式EAV/SAV時序碼、外部視頻同步信號以及I2C通信協議。
