TDA8777 Datasheet | NXP Semiconductors

description The TDA8777 consists of three separate 10-bit video Digital-to-Analog Converters (DACs) with plementary 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. The TDA8777 has a Power-down mode to reduce power consumption during inactive periods. The TDA8777 is fabricated in a CMOS process that ensures high functionality with low power dissipation. 2.
