It consists of a high speed, 10-bit, video D/A converters; a standard TTL input interface; and a high impedance, analog output, current source.
The ADV7128 has a 10-bit pixel input port.
A single +5 V power supply, an external 1.
23 V reference and pixel clock input are and all that are required to make the part operational.
The ADV7128 is capable of generating video output signals which are compatible with RS-343A, RS-170 and most proposed production system HDTV video standards, including SMPTE 240M.
The ADV7128 is fabricated in a +5 V CMOS process.
Its monolithic CMOS construction ensures greater functionality with low power dissipation.
The ADV7128 is available in a 28lead small outline IC (SOIC).
PRODUCT HIGHLIGHTS 1.
Fast video refresh rate, 80 MHz.
2.
Guaranteed monotonic to 10 bits.
Ten bits of resolution allows for implementation of linearization functions such as gamma correction and contrast enhancement.
3.
Compatible with a wide variety of high resolution color graphics systems including RS-343A/RS-170 and the proposed SMPTE 240M standard for HDTV.
4.
Combined with a numerically controlled oscillator (AD9955), it forms a complete frequency synthesizer (DDS).
5.
Using the parts reduced power output DAC modes, it...
