Dual 50MHz to 1000MHz High-Linearity, Serial/Parallel-Controlled Digital VGA General Description The MAX2063 high-linearity, dual digital variable-gain amplifier (VGA) operates in the 50MHz to 1000MHz frequency range. Each digital attenuator is controlled as a slave peripheral using either the SPI-patible interface or a 5-bit parallel bus with 31dB total adjustment range in 1dB steps. An added feature allows “rapid-fire” gain selection between each of four steps, preprogrammed by the user through the SPI-patible interface. A separate 2-pin control allows the user to quickly access any one of four customized attenuation states without reprogramming the SPI bus. Since each of...
