TDA8777
Triple 10-bit video DAC, up to 330 MHz sample frequency
Rev. 03 — 15 August 2005
Preliminary data sheet
1. 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.
