TDA9910
12-bit, up to 80 Msample/s, Analog-to-Digital Converter (ADC)
direct/ultra high IF sampling
Rev. 02 — 9 December 2004
Objective data sheet
1. General description
The TDA9910 is a 12-bit Analog-to-Digital Converter (ADC) optimized for direct 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 fixed 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 flexible 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 flexibility in front-end aliasing filter strategy.
Released in HTQFP48, it keeps the industry's smallest ADC of its category.
