Philips Semiconductors
Product specication
10-bit, 1000 Msps Digital-to-Analog
Converter (DAC)
TDA8776A
FEATURES
10-bit resolution
Conversion rate up to 1000 MHz
10K/100K ECL input levels
Internal reference voltage generator
No deglitching circuit required
Internal input register
Power dissipation only 925 mW (typical)
Internal 50 output load (connected to the analog
ground)
Very few external components required.
APPLICATIONS
High-speed digital-to-analog conversion for:
High resolution video and graphics
Direct digital synthesis (DDS)
Telecommunication
High-speed modems.
GENERAL DESCRIPTION
The TDA8776A is a 10-bit Digital-to-Analog Converter
(DAC) for high resolution video and other high frequency
applications. It converts the digital input signal into an
analog output voltage at a maximum conversion rate of
1000 Msps. No external reference voltage is required and
all digital inputs are 10K/100K-ECL compatible.
QUICK REFERENCE DATA
Notes
1. D0 to D9 connected to either HIGH or LOW level, CLK is HIGH and CLK is LOW.
2. The analog output voltages (VOUT and VOUT) are negative with respect to AGND (see Table 1). The external output
resistance between AGND and each of these outputs is typically 50
.
3. A warm-up time is necessary to reach optimal performances.
