TDA9912HL

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.
