128 Channel Analog Front-End

PMCC_XCM_64X64_A IP block is a 128 channels analog front-end. The IP block consists of 128 variable gain amplifiers (VGAs), 128 2-bit digitizers, bias and calibration circuits. It converts analog input signals in the 10MHz-500MHz range to digital data. The nominal sampling frequency is 1GHz. The IP block combines 16 groups of 8 analog front-ends in each group. The biasing currents, the ADC conversion range and the targeted VGA gain level are programmable. These features are used in production for operational margin estimation. Control functions and layout configuration of the IP block can be customized upon special agreement.
