General description

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.
