General description
The TDA9910 is a 12-bit Analog-to-Digital Converter (ADC) optimized for direct Input
Frequency (IF) sampling, and supporting the most demanding use conditions in ultra high
IF radio transceivers for cellular infrastructure and other applications such as wireless
access system, optical networking and xed telecommunication. Thanks to its broadband
input capabilities, the TDA9910 is ideal for single and multiple carriers data conversion.
Operating at a maximum sampling rate of 80 Msample/s, analog input signals are
converted into 12-bit binary coded digital words. All static digital inputs are CMOS
compatible. All output signals are LVCMOS compatible. The TDA9910 offers the most
possible exible acquisition control system thanks to its programmable Complete
Conversion Signal (CCS) that allows to adjust the delay of the acquisition clock.
Thanks to its internal front-end buffer, the TDA9910 offers the lowest input capacitance
(< 1 pF) and therefore the highest exibility in front-end aliasing lter strategy.
