TDA8777数据手册恩XP中文资料规格书

描述 Description

General description
The TDA8777 consists of three separate 10-bit video Digital-to-Analog Converters (DACs) with complementary outputs. They convert the digital input signals into analog current outputs at a maximum conversion rate of 330 MHz. The DACs are based on current source architecture.
A sync pulse can be added to the green signal (sync-on-green) to allow devices driven by the video DAC to be synchronized.
