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.
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.
