ADC1207S080 - 12-bit Analog-to-Digital Converter
ADC1207S080 - 12-bit Analog-to-Digital Converter
The ADC1207S080 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 infrastructure, optical networking and fixed telecommunication.
Due to its broadband input capabilities, the ADC1207S080 is ideal for single and multiple carriers data conversion. Operating at a maximum sampling rate of 80 MHz, analog input signals are converted into 12-bit binary coded digital words. All static digital inputs are CMOS compatible. All output signals are Low-Voltage Complementary Metal-Oxide Semiconductor (LVCMOS) compatible.
The ADC1207S080 offers the most flexible acquisition control system because of its programmable Complete Conversion Signal (CCS) that allows to adjust the delay of the acquisition clock.
The ADC1207S080 offers the lowest input capacitance (< 1 pF) and therefore the highest flexibility in front-end aliasing filter strategy because of its internal front-end buffer.
