Product specification
9-bit analog-to-digital converter
for digital video
TDA8761A
FEATURES
9-bit resolution
Sampling rate up to 40 MHz
DC sampling allowed
One clock cycle conversion only
High signal-to-noise ratio over a large analog input
frequency range (8.2 effective bits at 10 MHz full-scale
input at f
clk
= 30 MHz)
No missing codes guaranteed
In Range (IR) CMOS output
Levels TTL and CMOS compatible digital inputs
3 to 5 V CMOS digital outputs
Low-level AC clock input signal allowed
External reference voltage regulator
Power dissipation only 158 mW (typical)
Low analog input capacitance, no buffer amplifier
required
No sample-and-hold circuit required.
APPLICATIONS
Analog-to-digital conversion for:
Video data digitizing
Digital Video Broadcasting (DVB)
Cable TV.
GENERAL DESCRIPTION
The TDA8761A is a 9-bit Analog-to-Digital Converter
(ADC) for professional video and digital video set box
applications. It converts the analog input signal into 9-bit
binary-coded digital words at a maximum sampling rate of
40 MHz. Its linearity performance ensures the required
conversion accuracy in the event of 256-QAM
demodulator concept and for all symbol frequencies.
All digital inputs and outputs are TTL and CMOS
compatible, although a low-level sine wave clock input
signal is allowed.
